The micro–composition of the soil is closely related to its engineering properties. In Northeast China, seasonal freezing and thawing can induce deterioration of the physicomechanical characteristics of saline soil, which can ultimately lead to engineering failures and geological disasters. To investigate the micro composition evolution including the microstructure and grain size distribution of saline soil under the influence of freeze–thaw cycles, mercury intrusion porosimetry (MIP) and laser particle size analysis (LPSA) were used to test undisturbed saline soil specimens undergoing different freeze–thaw cycles. The pore size distribution curves showed a double–peak shape and the grain size distribution curves showed a bidirectional change. Overall, the pores >0.4 μm increased while the pores smaller than 0.4 μm decreased with increasing freeze–thaw cycles. Moreover, the grain size distribution showed a different changing trend at a pore diameter of approximately 10 μm. During the whole freeze–thaw cycle process, the fragmentation of coarse particles (> 10 μm) and the aggregation of fine particles (< 10 μm) were evident, causing the transformation of different pore sizes, and the bidirectional change existed synchronously in the whole process. The freeze–thaw cycles for saline soil caused the lyotropic salt precipitation and dissolution and the ice volumetric expansion and ice segregation to change the grain size distribution leading to the evolution of pore distribution, ultimately changing the soil micro–composition and resulting in the change of macro engineering characteristics. The study is useful for understanding the change in the engineering properties of saline soil under freeze–thaw cycles from a microscale perspective.

This study investigates the effect of spatial variability on the stability of a real 3D slope subjected to earthquakes by conventional Monte Carlo simulation (MCS) and a stochastic response surface method. The stochastic response surface method used in this study (VRSRSM) was combined with a variance reduction method due to spatial averaging of soil parameters in slope failure to reduce a large computational load due to the realization of spatially correlated input parameters in three-dimensional space. In order to verify the applicability of the stochastic response surface method with a variance reduction method for 3D slope reliability, the safety factor for a simple 3D slope under non-seismic and seismic conditions was analyzed by MCS and VRSRSM. The VRSRSM was applied to risk evaluation of deep-seated landslides caused by the 2016 Kumamoto earthquake along with backcalculation of strength parameters based on the slope failure geometry and field investigation.

This paper presents the physical properties of pumice fall deposit sampled at Takanodai, Minami-Aso village, Kumamoto Prefecture in JAPAN, where long runout landslide took place due to the main shock from the 2016 Kumamoto earthquake. A series of direct box shear tests under various conditions such as constant-stress, constant-volume and cyclic-shear loading conditions was conducted for undisturbed and unsaturated samples of pumice fall deposit to evaluate shear strength properties and seismic behaviors. Based on the slope stability analysis followed by the soil runout analysis at Takanodai, the pumice fall deposit layer shows a large horizontal displacement. While pumice fall deposit layer has enough stability under a normal condition, the strength reduction induced by the soil particle crushing is considered to be one of the factors caused a long runout landslide at the above site.

This paper presents a formula to estimate the stable weight of a rubble mound for breakwaters, considering the tsunami-induced overflow and seepage flow, based on the theoretical force balance among the frictional resistance of the rubble mound, the tractive force of the water flow over the caisson to the rubble mound and the seepage force of the rubble mound through the breakwaters. A series of hydraulic model tests was conducted on the scale of 1/100 for the Kamaishi Harbor Mouth Breakwaters in order to confirm the effectiveness of the proposed formula. Using the test results, the stability of rubble mounds for breakwaters was evaluated from the geotechnical engineering and hydrodynamical points of view.

Phytoremediation is recently paid attention as one of the low-cost and sustainable methods especially for remedying heavy metal contaminated ground. However, there are several cases that it may not be effective because plant growth is often dominated by geotechnical and climatic environments. To perform this method efficiently and effectively, it is necessary to evaluate the relationship between plant growth and geo-chemical and physical environments. Therefore, authors developed "geo-environment - plant root growth simulator" in order to estimate the future distribution of chemical substances in the ground. The explicit-finite-difference-method was applied on the simulator. The movement of soil moisture and water soluble substance can be modelled by Richard's equation and advection-dispersion-equation. As a targeted pollutant, hexavalent chromium (Cr6+) was chosen. This paper conducted a parametric study with changing three parameters such as the initial length of root (L), solute absorption speed of root (K-p), and root length density (L-v2) about the movement of chemical substances in unsaturated ground on a cylindrical coordinate system. As a result, in this numerical condition, the initial length of root had the largest effect for phytoremediation in the three parameters.

Authors have been working on greening experiment of precious medicinal plant licorice (Glycyrrhiza uralensis Fisch.) by using developed GSMs (Greening Soil Materials) in non-habitat area of Southern Mongolia to combat for progression of desertification. GSM is made of sand and compost that can be taken around targeting ground. It can be controlled moisture and nutrient retention capacity in shallow part of ground for growing plants healthily by fixing the mixing ratio of the materials. It can be made and set easily and affordably. In this paper, for clarifying key geo-environmental factors of GSM to survive seeds of licorice, principal component analysis, and for making estimation formula of survival of licorice, multiple regression analysis were conducted. 13 kinds of parameters important for growth of plant such as volumes per one seed of licorice, water contention, CaCO3-Ca, pH, EC, various water soluble, and exchangeable cations of GSM were used by these analysis.

Plant has a strong influence on shear strength properties of soil. Recently, slope protection method using plant is increased in public works, thus mechanism of preventing slope failure by root is expected to be clarified. In this study, in order to clarify relationships between plant and shear strength properties of soil, shear box tests of soil with plant were conducted. The strength properties of soil focusing on the number of plant were evaluated by measuring shear stress and strength parameters of soil with plant. Furthermore, vertical displacement, horizontal displacement and bioelectric potential of stem and root were measured during shear test. The relationship between bioelectric potential of plant and shearing behaviour of soil was considered. As a result of shear box tests, when plant was existed in the area of shear box, strength parameter c(d), phi(d) was increased respectively compared with the area without root. Furthermore, amplitude of bioelectric potential was changed after maximum shear stress was shown.

In order to improve the stability of breakwater due to tsunami-induced overflow and seepage flow, it is effective that putting armor blocks on the harbor-side mound of breakwater. A hydraulic model experiment for the model of Kamaishi Bay breakwaters under tsunami condition was conducted to evaluate the extent of armor block damage focusing on the weight, the height ratio (the ratio of the armor block height to the armor block diameter) and the open ratio of the armor block (the ratio of the open volume to the armor block volume).

Desertification is one of the most critical geo-environmental problems. The purpose of this research is to develop the sustainable and high added value anti-desertification method by utilizing medicinal plant licorice (Glycyrrhiza uralensis). It is one of the most valuable medicinal plants which grow naturally in arid region, such as Mongolia and China, but the distribution area is decreasing recently. Therefore, planting licorice in Mongolian arid region by simple and inexpensive method could be "sustainable and high added value greening", which can satisfy geo-environmental improvement, expansion of distribution area of licorice, and conservation of natural ecological resource at the same time. In order to achieve these purpose, we developed Greening Soil Material (GSM), which is pipe-shaped and has several times higher water and nutrient retention capacity for planting licorice in deteriorated area. In this paper, cultural experiments were conducted in sandy ground simulated arid region and Non-habitat of licorice in Mongolia by using GSM in order to grasp suitable soil water and calcium condition, setting direction and outer layer processing were examined for survival and growth of licorice. It could be revealed that 1) medicinal ingredient in the root tended to become higher by using GSM whose available moisture has 3 to 10 times higher than the Mongolian soils, 2) root length and weight became bigger by using GSM which contains around 18% of CaCO3, 3) survival rate of the conditions setting GSM horizontally was higher than the conditions setting GSM vertically, 4) survival rate of the conditions which GSM contained 10% of compost or potting soil as the dry weight ratio was higher than other conditions, and 5) the more Ca2+ had been kept in the GSM, the higher survival rate was.

&nbsp;In order to recycle dredged soil, our research group developed interlocking blocks from dredged soil. Dredged soil interlocking blocks (350 mm in width, 350 mm in depth and 100 mm-150 mm in height) were made from soft clay dredged at the Kanmon Waterway. They were produced with the constant pressure 5 MPa and cement content of 15 %, 20 % and 25 % per the dry weight of clay. On the other hand, Katagiri³⁾ developed dredged and dewatered soil. The unconfined compression test was carried out to investigate material characteristics of dredged soil interlocking blocks and dredged and dewatered soil. The following conclusions are obtained: (1) There was relationship between unconfined compressive strength and dry density about dredged soil interlocking block, but there wasn't much relationship about dredged and dewatered soil. (2) There was relationship between unconfined compressive strength and water content about dredged soil interlocking block, but there was no relationship about dredged and dewatered soil. (3) Inclination of relationship between unconfined compressive strength and water-cement ratio was almost the same about dredged soil interlocking block cement content of 20 % and dredged and dewatered soil cement content of 15 % and 20 %.

&nbsp;The Tohoku-Pacific Ocean Earthquake and tsunami gave serious damages to many breakwaters in Tohoku region, Japan. The major cause of failure is the tsunami wave force. However, a new type of failure is confirmed: caused by scouring of the harbor side mound by overflow and seepage flow. In fact, the cause of failure of 9 among the 22 destroyed breakwaters was scouring of the mound and any effective measurement against that cause has not been invented. Therefore, in the previous research we developed a new method to calculate the stable weight of an armor block in consideration of the overflow and seepage flow from the view point of the geotechnical engineering. In this paper, using this method, the most effective shape of the armor block will be described. Furthermore, some sort of hydraulic model experiments with Kamaishi bay breakwater as a subject have been done in order to see the difference of damage in terms of different 3 height ratio (given by height divided by radius of blocks) shapes of blocks and 2 ways of laying blocks. Thorough this methodology the optimum proportion of the block which has a hole like annulus was found. The hydraulic model experiments also revealed that the most effective height ratio was 1/2 out of 1/4, 1/2 and 3/4. In conclusion, it can be reasonable to use this methodology to determine the optimum shape of armor blocks only under the situation of overflow, however when it comes to the time of only seepage flow, more investigation must be done.

In order to recycle dredged soil, our research group developed interlocking blocks from dredged soil. Dredged soil interlocking blocks (350 mm in width, 350 mm in depth and 100 mm-150 mm in height) were made from soft clay dredged at the Kanmon run. They were produced with the constant dehydration pressure 5 MPa and cement content of 15%, 20% and 25% per the dry weight of clay. The unconfined compression test and bending test were carried out to investigate material characteristics of dredged soil interlocking blocks in the water for six months. On the other hand, in order to check the effect of interlocking blocks, a road was constructed by using interlocking blocks on the surface and, as a roadbed material, dredged and dehydrated soil and crushed stone for mechanical stabilization were used. Characteristics of dispersion of traffic load and settlement were evaluated by running experiments. Stress was measured by four earth pressure gauges and settlement was measured by surveying. The following conclusions are obtained: (1) There was close relationship between unconfined compressive strength and water-cement ratio. Therefore, it is concluded that unconfined compressive strength of dredged soil blocks are controlled by water-cement ratio. (2) Dredged and dehydrated soil can disperse traffic load effectively. (3) Soil-concrete blocks can't disperse traffic load effectively, but have sinking suppressing effect when using dredged and dehydrated soil as roadbed material.

Desertification is a kind of land degradation phenomena which can be caused by natural or artificial geo-environmental problems. Especially, Asia is considered to be highly vulnerable to desertification than other area. Authors have been trying to develop the measures of anti-desertification which is sustainable and with highly added value. In order to accomplish this purpose, licorice (Glycyrrhiza uralensis Fisch.), a kind of medical herb grows natively in Chinese and Mongolian arid region, was experimentally planted in Mongolian arid area. It is one of the most demanded medicinal herbs in Japanese pharmaceutical industry, but numbers of native licorice in these regions are decreasing due to several causes. Authors developed Greening Soil Material (GSM) as one of the effective methods to plant licorice where once was habitat of licorice. It is pipe-shaped with more than 10 times higher water and nutrient holding capacity compared to the deserted ground. The experimental research using GSM has been conducted in Southern Mongolia. From the results of past experimental study, important factors for survive and healthy growth of licorice in arid area were revealed: volume, water content, and calcium content in GSMs. In order to suggest the suitable conditions for survive of licorice in its non-habitat area, this paper presents the relationship between survival ratio of licorice and volume of GSMs, water content of GSMs, and calcium content of GSMs and quantifies these relationships.

When The Tohoku-Pacific Ocean Earthquake occurred on the March 11th, 2011, harbor facilities such as breakwaters and tide embankments suffered serious damages from the Tsunami. The following three mechanisms are considered to be related to the collapse of the breakwater: 1) scouring of the mound due to overflow, 2) the horizontal force originated from the difference of water level between the sea side and the harbor side on the breakwater, and 3) reduction of bearing power of the mound induced by seepage flow. However, the mechanism of the instability of the rubble-mound by overflow and seepage flow induced by tsunami is not fully clarified. In this study, the formula to calculate the stable weight of rubble-mound was proposed in consideration of the overflow and seepage flow, and hydraulic model experiments were conducted on Kamaishi Bay breakwaters as the subject in order to confirm the effectiveness of the proposed formula. Using the results, the stability of the breakwater was evaluated from the geotechnical engineering point of view.

Development of technique which can restrain the progress of desertification sustainably and voluntary is taken place by using valuable herbal plant licorice (Glycyrrhiza uralensis). Firstly, prehension about geo-environment included weather condition around the study areas is needed to succeed the technique. This paper indicates the results of geo-environmental survey were held in the arid area where licorice lives natively and doesn't live. And this paper also shows the consideration about difference between habitat and non-habitat of licorice, and relationships between physical properties and chemical properties in the ground. The experimental results are concluded that 1) The arid ground in Bogd soum and Baatsagaan soum in Bayanhongor province, Mongolia, the ground was heterogeneous whose grain size properties are between sand and silt within the depth of 1 ~ 2 m. 2) Water content in the ground which licorice could be lived was at least more than 5 %, and keeping groundwater level and ground moisture could be important for bringing up seedlings of licorice. 3) The silty layers has relatively higher available moisture than the sandy layers, and calcium carbonate (CaCO₃) accumulated in the silty layers, so that they had higher pH and EC values than sandy layer.
