摘　　要：瀑布沟水电站地下厂房开挖初期受停工影响,造成洞室围岩变形、松动范围增大。后期开挖过程中,通过松动圈检测,随时掌握围岩变形状况,并在施工过程中严格按照开挖爆破试验参数进行施工,加强安全监测分析与反馈,保证了工程施工质量,同时也加快了施工进度。The deformation and loose range of Pubugou underground powerhouse wall rock is increased as the suspension of construction after the vault layer excavation completed, but the acoustic detection shows that the loose range is limited before project resumption. The quality of following excavation was guaranteed by blasting which was strictly in accordance with the blasting test parameters and the monitor and analysis, and the progress was also speeded up.
