Abstract The underground powerhouse of Yangfanggou hydropower station is a typical large-span and high side wall cavern group. The geological condition is complex. The stability analysis of high side wall and the rock pillar between caverns is key for cavern design. Based on in-situ test data，using boundary displacement condition regression method，the initial geostress field is constructed. The stability of surrounding rock of underground caverns is analyzed by FLAC3D. The deformation and stress characteristics，plastic zone distribution field and force of support are obtained. The integrated stability of underground powerhouse is evaluated. The study results provide scientific basis and technical advice for caverns design.

Key words： hydraulic engineering Yangfanggou hydropower station underground powerhouses high side wall initial geostress field stability of surrounding rock
