摘要： 基于某水电站近坝库岸边坡滑坡体的工程地质调查，分析了该滑坡体失稳的成因机理，采用反算法和工程地质类比法确定其物理力学参数，基于剩余推力法计算了滑坡体在不同工况与物理力学参数组合下的边坡稳定安全系数，最后对库岸滑坡体的治理措施提出了建议。

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.
