摘　　要：在分析小锡伯提水库滑坡体地质环境条件和形成原因的基础上,建立二维模型,利用极限平衡法和强度折减有限元法分析滑坡体的稳定性。分析结果表明,滑坡体在天然状态下处于欠稳定状态,不满足工程长期安全要求。结合搜索得到的滑动面和滑坡体自身的地质特点,提出了削坡治理方案,并用极限平衡法校验其在各种工况下的安全性。Based on the analyses of engineering geological conditions and forming reason of the landslide in Xiaoxiboti Reservoir, a 2-D model is established to analyze the stability of landslide by limit equilibrium method and shear strength reduction method. The calculation results show that the landslide is not stable in natural, and the safety factor of the landslide can＇t meet engineering requirements. According to the critical slip surface which being searched and the characteristics of landslide, a scheme of slope cutting is proposed, and then the stabilities of landslide under different operation conditions are checked by limit equilibrium method.
