摘要
针对小湾水电站尾水隧洞系统1号尾水出口检修闸门竖井开挖支护施工中,上游侧闸门井壁产生失稳坍塌的情形,阐述了井壁破坏前后的施工状况,从不同角度分析了形成塌方的原因,提出了预防及改进的措施。
During the borehole excavation and supporting construction of No. 1 tailrace export gate in Xiaowan Hydraulic Power Station, borehole wall of side gate collapses severely in upstream. The construction situations of borehole wall before and after collapse are introduced. The cause of collapse is analyzed from many aspects in detail, and measurements for prevention and improvement are suggested.
