摘　　要：以雅砻江流域某水电站上游库区滑坡体为研究对象,采用刚体极限平衡法和有限元法,对自然边坡在天然工况下的抗滑稳定性进行对比分析,探明两种方法在边坡稳定性分析中的差异,并对库区自然边坡的天然稳定性进行评价。Taking the landslide body located in the upstream reservoir area of a hydropower plant on the Yalongjiang River as an object of study and using the rigid body limiting equilibrium method and the finite element method,this paper makes a comparison and analysis of the stability against sliding of the natural slope under the natural operating condition.The paper then verifies the difference in analysis of the slope stability between the two methods and makes an assessment of the natural stability of the natural slope in the reservoir area.
