【摘要】 鱼洞河滑坡是水布垭坝址区十分重要的地质灾害隐患。在宏观工程地质条件研究的基础上，对鱼洞河滑坡进行了二维弹塑性有限元变形破坏机理分析，刚体极限平衡ＪＡＮＢＵ法、非垂直条块划分法计算，失稳概率及可靠度分析，Ｓａｒｍａ法强度失稳分析，最后进行了若干稳定性影响因素的敏感分析及正交试验分析。更多还原

【Abstract】 Yudonghe landslide is the main hidden danger of geological hazard at shuibuya dam region.On the base of researches to the macroscopic engineering geological condition, a series of analysis have been done witch include the analysis of deformation destruction mechanism under two dimension elasto-plasticity finite-unit;the calculation with rigid body limit equilibrium JANBU and invertical strip dividing method; the analysis on the unstability probability and the reliability;the analysis to the strenth unstability with sarma method;the analysis of the susceptibility with some stability effect factors and the stracght join test to Yudonhe landslide.更多还原
