摘　　要：高陡边坡存在裂隙发育、风化严重、卸荷强烈等不良的地质现象,直接影响到高边坡的稳定性。该文分别采用三维有限元强度折减法和二维刚体极限平衡法,对和平水库右坝肩边坡在开挖支护后的稳定性进行分析。研究结果表明,和平水库右坝肩边坡在完建工况下的稳定性满足规范要求,开挖和支护措施合理可行。There are some bad geological phenomena in high and steep slope,such as crack development,serious weathering,strong unloading and so on,which directly affect the stability of high slope.In this paper,the three-dimensional finite element numerical strength reduction method and the two-dimensional rigid body limit equilibrium method are used to analyze the stability of the right abutment slope of Heping Reservoir after excavation and support.The results show that the stability of the right abutment slope of Heping Reservoir meets the requirements of the code,and the excavation and support measures are reasonable and feasible.
