某水电站开关站边坡稳定性分析

Slope Stability Analysis of Switch Station of a Hydropower Station

通过地表地质调查及自然边坡现状对某水电站开关站边坡稳定性进行宏观判断,并采用极限平衡法对边坡在天然、地震、暴雨、暴雨+地震等工况下的稳定性进行定量计算,辅以赤平投影对工程开挖边坡稳定性进行分析,依据计算与分析成果针对性提出边坡开挖处理建议,为工程施工及安全管理提供科学依据。

Based on the surface geological survey and the current situation of natural slope, this paper makes a macro judgment on the slope stability of the switchyard of a hydropower station, and uses the limit equilibrium method to quantitatively calculate the stability of the slope under the conditions of natural, earthquake, rainstorm, rainstorm + earthquake, with the help of stereographic projection to analyze the stability of the excavation slope of the project. According to the calculation and analysis results, the excavation suggestion of the slope is proposed to provide scientific basis for engineering construction and safety management.
