针对溧阳抽水蓄能电站地下厂房的工程地质条件,对地下厂房整体支护设计参数进行了分析,对F54断层和开挖过程中情况异常部位采取了有针对性的加固措施。监测数据表明,地下厂房围岩整体稳定,采取的支护设计方案和对特殊部位的加固措施是合理的,可为今后复杂地质条件下地下厂房围岩稳定分析与支护设计提供参考。
According to the engineering geological conditions of underground powerhouse of Liyang Pumped Storage Power Station, the design parameters of the overall support of underground powerhouse are analyzed, and the reinforcement measures are taken for the fault F54 and the abnormal parts during excavation. The monitoring data show that the whole surrounding rock of the underground powerhouse is stable, the support design scheme adopted and the reinforcement measures for special parts are reasonable, which can provide references for the stability analysis and support design of the surrounding rock of underground powerhouse in complex geological conditions in the future.
