摘　　要：为了安全经济地选择惠州抽水蓄能电站地下厂房的支护方案,对地下洞室开挖过程进行三维有限元分析,并根据计算结果选择支护方案,再对支护方案进行综合方案比较分析,研究了喷混凝土、锚杆等支护措施对围岩的加固作用,得到了一些对设计及后续施工有指导意义的有益结论。In order to choose safe and economical supporting system of the underground powerhouse for the Huizhou Pumped Storage Hydropower Station, a series of 3--D FEM analyses are carried out to simulate the excavation sequence. According to the elementary results of the analyses, supporting system is chosen and analyzed comprehensively through comparison of the schemes. The effects of the concrete spurting and anchoring to reinforce wall rock are discussed, and the beneficial conclusions for the design of supporting system are derived to direct the following constructions.
