| Abstract |
In slope stability analysis for landslides, mountains have various slopes and geographical features, and hence it is necessary to estimate stability using rigorous analysis methods. In this study, after the analysis of infiltration behavior through unsaturated layers due to rainfall, the stability of landslide was estimated to account for the variation of pore water pressures. In the analysis of slope stability, a three-dimensional slope analysis was compared with an infinite slope analysis in a case study of terrain in which an actual landslideoccurred. In the three-dimensional slope stability analysis, it was found that the location of the failure and the failure area were predicted accurately based on the detailed geological information despite the variation of geographical features. |
