摘  要：为确定五强溪电厂1^# 变形体的稳定性，采用刚体极限平衡法中的传递系数法计算变形体的整体稳定性，采用Slide模块计算局部稳定性。计算分析结果表明：变形体的整体稳定性在处于山脊部位的3-3’剖面处相对较差，且各个剖面在假定界面3的情况下，安全系数均偏低，整体稳定性不佳；变形体的局部稳定性较差，如果发生破坏稳定的情况，极大可能会导致局部失稳的发生。因此应加强对该变形体的监测，并采取必要的工程措施防止失稳的发生。

Abstract: In order to determine the stability of 1^# deformation body of Wuqiangxi Power Plant, the transfer coefficient method in rigid-body limit equilibrium methods is used to calculate the overall stability of the deformation body. The Slide module is used to calculate the local stability. The analysis results show that the overall stability of the deformed body is relatively poor in the 3-3' section located at the ridge, and the safety coefficient of each section is low. The overall stability is poor under the assumption of interface 3. The local stability of the deformed body is poor. If the situation of instability occurs, there is a great possibility that it will lead to the occurrence of local instability. Therefore, the monitoring of the deformation body should be strengthened. Necessary engineering measures should be taken to prevent the occurrence of instability.

Key words: deformation body; stability of slope; rigid-body limit equilibrium methods; stability calculation; evaluation
