Abstract: In construction of hydropower projects, landslide accident caused by slope excavation is very common. How to scientifically analyze and evaluate the safety of engineering slope is an important issue. This paper discusses the difference between the two methods, namely the rigid body limit equilibrium method and the finite element method, and provides scientific basis for project construction.

Key words: rock slope, stability, rigid body limit equilibrium method, finite element method

摘要： 水电工程建设中，边坡开挖导致的滑坡事故屡见不鲜，如何科学分析和评价工程边坡的安全稳定是亟待解决的重要课题。利用刚体极限平衡法及有限元法对某水电站大坝右岸缆机平台边坡典型剖面稳定性进行计算，探讨了两种方法计算结果的差异，分析了边坡的静力特性，为该工程建设与安全运行提供科学依据。
