Abstract: Based on the investigation of the engineering geological conditions in the reservoir bank slope，the failure mechanism of the reservoir bank landslide has been studied. The physical and mechanics parameters are determined by the inverse analysis method and the engineering geologic analogy method. The safety factors of the slope under different working conditions and parameters are obtained based on the residual thrust method. Finally, the engineering treatment of the landslide has been proposed.
