摘　　要：龟山古滑坡体体积约2100万立方米,其稳定性直接影响电站的运行安全。首先分析了古滑坡体的边界条件和滑裂带力学参数取值,并指出岩质古滑坡稳定性分析中应注意的问题,然后分别使用极限平衡法和三维Flac方法分析了龟山古滑坡体的稳定性。最后根据稳定性分析结果提出了对龟山古滑坡体的处理建议。Guishan ancient rock slide, bulking about 2100×10^4m^3, lies above water inlet/outlet of lower reservoir of Baoquan Pumped Storage Power Station. The stability of the slide evidently affects safety of the pumped-storage power station. The paper first discussed boundary conditions and parameters on slide surface of the ancient slide, pointing out problems that should be paid attention to in stability analysis of ancient rock slide. Stability of Guishan ancient rock slide was then calculated by 2D （limiting equilibrium） and 3D （Flac） methods. Based on the calculations, remedy methods were finally suggested.
