复杂地质条件下地下厂房洞室群开挖顺序研究

Study on Excavation Sequence for Underground Powerhouse Caverns under Complicated Geological Conditions

复杂地质条件下大型地下厂房洞室群围岩稳定是岩石力学重大技术问题之一,也是施工中必须解决的问题,以江苏溧阳抽水蓄能电站工程为背景,对复杂地质条件下的大型厂房洞室群围岩稳定进行了系统分析,并通过分析制定出科学合理的开挖施工方案,确保实际施工的安全、进度,取得了良好成效。

The stability of the surrounding rock of large underground powerhouse caverns under complex geological conditions is one of the major technical challenges in rock mechanics,but it must be solved in the construction.The study systematically analyzes the stability of the surrounding rock of large underground powerhouse caverns under complex geological conditions for Jiangsu Liyang Pumped Storage Power Station,and strategizes a scientific and reasonable excavation scheme to ensure the safety and progress of the actual construction.
