摘　　要：溪洛渡水电站位于四川省雷波县和云南省永善县境内金沙江干流,为中国第二大水电工程。通过介绍溪洛渡水电站左岸主厂房在开挖过程中围岩变形状况,结合厂房围岩地质条件、监测数据及声波资料,对相互间影响关系进行分析,针对松弛、变形部位进行加固处理。Xiluodu hydropower station is located in the territory of Sichuan Province, Leibo county and the Yunnan province Yongshan County, the main stream of Jinsha River, China ＂s second largest hydropower project. Based on the deformation conditions of the surrounding rock in the process of excavation of the main plant on the left bank in Xiluodu hydropower station, combined with geological conditions, monitoring data and acoustic data of the powerhouse, the relationships of them were analyzed, and the flabby and deformed parts were reinforced.

关 键 词：围岩变形 松弛 监测分析 加固措施
