摘要
通过对溧阳抽水蓄能工程地下厂房安全监测资料的分析和对三大洞室监测数据的比较,揭示了开挖过程中导致地下洞室围岩产生较大位移的主要因素。结合施工过程及支护措施,重点分析了围岩位移及应力变化趋势,对溧阳抽水蓄能电站地下厂房开挖和安全监测提出了建议。
Based on the analysis of monitoring data of underground powerhouse and the comparison of monitoring data of three main caverns in Liyang Pumped-storage Power Station, the factors which lead to larger displacement of surrounding rocks of underground caverns during excavation period are revealed. Combining with excavation process and support measures, the trends of displacement and stress of surrounding rocks are analyzed, and meanwhile, some recommendations on underground powerhouse excavation and safety monitoring are proposed.
