2号引水竖井布置于CCS水电站压力管道上、下平段之间, 埋深超过500 m. 依据开挖揭示的地质条件, 竖井1 086~1 110 m高程段出露3条陡倾角断层及1条陡倾角侵入岩脉, 各结构面之间相互交切,在竖井后续开挖中, 易形成不稳定块体. 运用UNWEDGE软件分析可能形成不稳定块体的结构面组合, 计算其安全系数, 并对原设计支护参数进行调整, 及时预报, 确保竖井围岩稳定.

2#diversion shaft of CCS hydropower station locates between the upper and lower horizontal section of pen -stock,the depth is over 500m.According to the geological conditions exposed by excavation ,1 086 m~1 110 m elevation segment outcrops 3 steep faults and a steep dike ,and the structure surfaces cut with each other ,which is prone to form unstable blocks during the following excavation .The structure surface combination that could form unstable blocks in 1 040 m~1 086 m elevation segment and the safety factor are analyzed by UNWEDGE program .And the original design support parameters are adjusted with calculation results ,in order to ensure the stability of surrounding rock mass of shaft .
