Characteristics and Stability Analysis of Landslide in Three Gorges Reservoir Area in Fengjie County

Based on the study of engineering geology condition and basic properties of landslide in Three Gorges Reservoir area,the main factor inducing slope failure is analyzed.According to the test data of soil sample,the data of site investigation,the parameter of the landslide's stability and the anti-shearing strength parameters were gotten.Because of water in the reservoir of Three Gorges,the result of the stability of the main landslide and the sub-landslide under the different conditions were caculated.The results show that the main landslide is stable in different conditions while the sub-landslide is in critical creeping motion when the landslide body is in water-saturation.Therefore,this landslide need to be controlled as soon as possible.
