On the basis of analysing basic features of Shiliushubao landslide, the landslide ’ s deformation and development tendency are quantitatively studied by using FLAC 3D program. The results accord with monitoring results. The results are indicated that reservoir impounding accelerates the landslide ’ s deformation, and the variation of reservoir water level is key factor of affecting the deformation; The landslide has the characters of pull-behind movement according to the displacement of the landslide body gradually reducing from leading edge to trailing edge; Excavating and deloading slow down the landslide ’ s deformation in the certain degree. On the basis, the deformation developmental tendency of Shiliushubao landslide is predicted by the established simulating model.
