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.

Key words: back analysis of initial geostress, opening’s spacing, excavation sequence, reinforcement effect, stability of surrounding rock
