Groundwater remarkably affects the strength and deformation of rock mass. It is underground fissure water that lowers the strength of rockmass and weakens stability of surrounding rock. In order to reflect the influence of groundwater on the stability of Dagangshan large-scale underground power house
according to coupling action mechanism of seepage and rock mass structure
this paper utilize the program of FLAC3D is appliced to analyze its stability under the action of groundwater. Computational results indicate that although the coupling action is unfavorable to the stability of surrounding rock
the reinforced underground cavern groups have been stable.
