溧阳抽水蓄能电站地下厂房围岩稳定分析与支护设计

Surrounding Rock Stability Analysis and Support Design for Underground Powerhouse of Liyang Pumped-storage Power Station

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。

Based on engineering geological conditions of underground powerhouse in Liyang Pumped--storage Power Station, the support parameters of underground powerhouse are analyzed. The special measures are taken for reinforcing F~ Fault zone and abnormal locations emerged in excavation. The current monitoring data show that the surrounding rock of underground powerhouse is stable, so the support design and reinforcement measures are reasonable. This research can provide reference to the analysis of surrounding rock stability and the support design of underground powerhouse with comolicated zeolo^ical conditions.
