<p>Soft and heterogeneous ground is widely distributed in Japan. When embankment is built on soft ground, it is necessary to conduct ground survey and set ground improvement range. The ground improvement range is determined by analysis simulation, and various parameters are necessary for analysis. In this research, we discuss the difference of results by analysis parameters set from the ground survey results.</p>

<p>Airborne laser measurement has been widely known as a surveying technique for acquiring topographic data with a high accuracy, and it has been lately utilized as a differential analysis for evaluating the amount of the sediment caused by a large-scale landslide. However, it is impossible to detect landslide behavior at speed of a few centimeters using aerial laser measurement. In this study, we have developed the analytic method to evaluate landslide variation amount with a high accuracy by discriminating characteristic land features from digital elevation model, which is called S-DEM or Substratum Digital Elevation Model, using laser point clouds at the position shifted from the ground with an arbitrary distance. We also describe the result that it is possible to predict the movement of debris slide occurred in the area of landslide using the method we developed.</p>
