摘　　要：首先根据地下结构问题的特点，简要介绍对地下结构工程进行三维弹塑性有限元分析应注意的几个问题．在此基础上，独立编制了相应的三维弹塑性有限元程序．应用该程序对天荒坪抽水蓄能电站地下洞室群进行了数值计算．计算中模拟了地下洞室的几种开挖顺序，考虑洞室间的相互影响及工作性态，从而确定出最合理的开挖顺序．The investigation of the behavior of underground structures shows that it is significant to make elasto plastic numerical analysis of underground structures.In this paper key problems are introduced of the numerical analysis by 3 D elasto plastic FEM for underground structures.The elasto plastic numerical analysis for the underground cavities of Tianhuangping Pumped Storage Power Station is performed by the computer code of 3 D FEM programmed by the authors.Several excavation procedures of underground cavities are simulated in the calculation.Finally,the reasonable excavation procedure is determined.
