摘　　要：某水电站地下厂房洞室群所处的区域地质条件相对较好,大部分位于Ⅲ类围岩中。影响地下厂房洞室围岩局部稳定的主要因素为结构面的组合与夹层的影响。文中通过计算分析并参考已建工程经验,选取了合理的开挖顺序及支护方式。The regional geological condition of the underground powerhouse cavern group of some hydropower house is better,most cavern are located in the surrounding rock of Class III. The structural surfaces combination and interlayer are the main factors for the local stability of surrounding rock for underground powerhouse cavern. Through the calculation and analysis and reference project experience constructed, the rational excavation sequence and the support mode are selected.
