摘　　要：西南某水电站大型倾倒变形体位于右坝肩顶部,其稳定性直接影响工程建设与运行的安全。在对该倾倒变形体的成因机制、结构、变形及力学特性进行分析的基础上,对开挖前的稳定性进行评价;结合施工处理方案及监测成果分析,对该倾倒体工程处理后的稳定性进行了复核评价。The large-scale toppling rockmass in a hydropower station in southwest China is located at the top of right abutment. Its stability directly affects construction and operation safety of station. The cause, structure, deformation and mechanical properties of the toppling rockmass are analyzed, and on the basis of analyses, the stability of the toppling rockmass before excavation is evaluated. Combining with engineering treatment scheme and monitoring data, the stability of the toppling roekmass after treatment is reviewed.
