摘　　要：蒲石河抽水蓄能电站地下厂房洞室群围岩类别为Ⅱ、Ⅲ类,以Ⅱ类为主。采用喷锚支护作为永久支护,用有限元计算和工程类比相结合的方法选定支护参数,用刚体平衡法对局部不稳定块体进行验算。研究结果表明,所采取的支护措施合理,地下厂房洞室群整体稳定。The surrounding rocks where the underground powerhouse caverns of Pushihe Pumped-storage Power Station located are classified as Class-II and III rock, and the majority is Class-II. The shotc rete is adopted for permanent support. The support parameters are determined by finite element calculation together with engineering analogy, and the check on local unstable blocks is made with rigid equihbrium method. The findings show that the underground powerhouse caverns are stable as a whole and the support is practical
