摘　　要：长河坝水电站开关站边坡的稳定性主要受斜向上游的f24断层控制，其变形破坏方式主要为旋转滑移拉裂型。本文采用三维有限元分析方法对该边坡的稳定性进行了分析，分析结果表明，工程边坡具有从下游往上游稳定性提高的趋势，边坡的稳定性具有一定的分区特征：下游侧0～35m斜坡处于不稳定状态，35~70m处于潜在不稳定状态，70m以上处于基本稳定状态。上述结果为工程边坡的支护措施设计提供了依据。The stability of the Switch station of Changheba hydroelectric power is control by F24 fault. Slipping fracturing damage exists as its main damaging fashion, and 3-Dfinite element analysis method is used to analyze its stabilization in this article. Calculated results show that the stability of project slope is enhanced from lower reaches to upper course and the division characteristic is seen clearly. During the flank of lower reaches on the side slope, the area from 0 to 35 meters is unstable, from 35 to 70 meters potentially unstable, and 70 meters upwards stable, therefore, the supporting measures of engineering slope are caught, according to above results.
