Summary: | 碩士 === 國立臺灣海洋大學 === 河海工程學系 === 97 === This thesis is aimed at investigate the main causes leading to catastrophic slope failure and to seek appropriate working methods and remedial countermeasures for engineering practices. The thesis is based on a case study of Hungtsaiping landslide district, and using the software of Geo-studio, developed by Calgary University, Canada. A 2-D analysis model is established and analyzed in order to build an analytical simultion of slope stability of transient seepage due to precipitation. The reliability and validity of the analytical model can be examined by comparing computed failure modes with those of field observations of Hungtsaiping landslide district. Further, the study analyzes the Digital Terrain Model, DTM of Hungtsaiping landslide district to discuss the causes of landslide, using ARCGIS.
The study simulates the relations of transient seepage and safety modulus of the slope stability, under different rainfall conditions of Hungtsaiping landslide district.The study using the Digital Terrain Model, DTM of Hungtsaiping landslide district to simulate aspects, slopes, groundwater levels, geology, rainfalls, and hydrology of the district to discuss the causes of landslides. In addition to that, the results of numerical analysis and the analysis of landslide classifications are used to set landslide factors of land on the slopes for further researches and the references of researchers and engineers.
