摘　　要：冶勒水电站地下厂房紧邻具有多期活动性的安宁河东支断裂北段,岩体历经多次构造运动作用,低序次的小断层和节理裂隙较发育,地质构造背景及工程地质条件复杂,开挖跨度大,岩体完整程度及成洞条件与国内已建地下厂房工程比较是相对较差的。为此,就地下厂房开挖揭示的工程地质条件、围岩特征及围岩稳定性进行了分析与评价。The underground powerhouse of the Yele Hydropower Station adjoins to the north section of Anninghe Dongzhi Fault with active characteristic. Due to many tectonic movement of rock body, small faults and fissures are developed so that its engineering geologic conditions are complex and its integrity and tunneling conditions of rock body is poorer than those of completed underground powerhouses at home. Therefore, this paper analyzes and assesses the engineering geologic conditions, features of surrounding rocks and the stability of surrounding rocks of the underground powerhouse of the Yele Hydropower Station.
