Outline of Final Research Achievements |
To evaluate the factors for the shallow landslide, this study conducted the laboratory experiments and in-situ monitoring of pore-water pressures in the soil layer. Our results indicated that the rapid responses of water movement and several groundwater water table formations were occurred. Also, this study conducted the spatial analysis of topography and field investigations which include the spatial distribution of spring and shallow landslide points, and the geophysical structure. Based on above results, this study proposed the evaluation methods of potential risk of shallow landslide in a hillslope.
