摘要
清江水布垭电站尾水隧洞开挖过程中,围岩稳定性是安全生产的关键技术问题,故在施工过程中进行了围岩收敛变形监测。介绍了隧洞收敛监测观测断面的布设、观测点的埋设、监测方案和数据处理,最后对围岩稳定位移和其达到基本稳定所需的时间进行了预测,同时对围岩及衬砌稳定性进行了分析和评价,并给出了监测所获得的结论。
In tunnels of Qingjiang Shuibuya power station digging, the stability of the surrounding rock was the key issue for the safety of mining. Deformation monitoring of surrounding rock was applied to the process of construction. This paper introduced the arrangement of monitoring cross-section, the means of implantation of measuring points, monitoring project and the method of handing with the data. The prediction of stable displacement and stable time was provided. Meanwhile, The stability of the surrounding rock and the lining was analyzed and evaluated. Some meaningful conclusions were obtained.
