摘要

对某水电站地下厂房采用有限元方法反演厂区初始地应力场。分别对地下厂房洞室群3个平行洞室的不同间距、洞室开挖的不同顺序以及施加锚杆和锚索后的方案与毛洞方案进行了分析比较。计算结果表明，经过适当优化后该洞室群在洞室布局、开挖顺序和支护参数等方面是安全可行的，各主要洞室群的稳定性总体较好。

Abstract

Finite element method(FEM)is adopted to back analyze initial geostress field around the underground power house of a hydropower station. Comparisons of different opening's spacings

different excavation sequences and reinforcement effect are made.The calculation result shows that after optimization

the openings’ layout

construction sequence and support parameters are safe and rational; the main openings are stable well.
