索风营水电站引水发电系统地下硐室群施工期安全监测

Safety monitoring on underground chambers and tunnels for Suofengying Hydropower Station during construction

介绍索风营水电站引水发电系统地下硐室群的施工期安全监测状况,对监测成果进行了整理与分析,分析评价了分层开挖施工过程与硐室围岩变形监测成果的影响因素关系,与其他已建工程的监测资料进行对比分析,对索风营水电站地下厂房的围岩稳定性作了初步评价。

The safety monitoring on the construction of the underground chambers and tunnels for the power house and the appurtenant works of Suofengying Hydropower Station is presented herein, in which the monitoring data are classified and analyzed; the relationship between the construction of the excavation in layers and the monitoring data from the deformation of the surrounding rock of the both the chambers and tunnels is evaluated with the comparative analysis on the monitoring data between this project and the other existed projects, and then the preliminary evaluation on the stability of the surrounding rock for the underground works of the hydropower station is made as well.
