介绍了溪洛渡水电站右岸尾水洞的施工进度安排和安全监测仪器布置。根据已获得的监测数据,对右岸尾水洞的围岩变形和围岩应力进行了分析,评价了右岸尾水洞围岩目前的稳定状态。分析结果表明,由于开挖支护控制较好,溪洛渡水电站右岸尾水洞围岩总体变形不大。
The construction schedule of the tailrace tunnel on the right bank of Xiluodu Hydropower Station and the arrangement of safety monitoring instruments are introduced. Based on the obtained monitoring data, the surrounding rock deformation and surrounding rock stress at the tailrace of the right bank were analyzed, and the current stability of the surrounding rock of the tailrace of the right bank was evaluated. The analysis results show that the overall deformation of surrounding rock of tailrace tunnel on the right bank of Xiluodu Hydropower Station is not large due to the better control of excavation support.
