摘要
大朝山电站地下厂房处于岩体弱面发育地带，其稳定性问题占有非常重要的地位．采用非线性有限元方法，考虑分步开挖情况，进行了6种工况的计算，并就其中两种工况分析了厂房的位移、应力分布和稳定性，比较了加拱顶和不加拱顶两种情况．最后，综合全部计算结果，对工程的整体稳定性做出了评价．
Dachaoshan Underground Hydropower Plant is located in the rock masses crossed by faults and interlayers. Its stability is of great importance. Six cases under different conditions are studied by nonlinear FEM. Excavation is taken into consideration in each case. The results of two cases-one takes the roof's support into account and the other doesn't-are given to analyze the displacement, stress distribution and stability of the underground plant. In the end, the stability of the whole plant is concluded.
