大岗山水电站地下厂房稳定性的流固耦合计算分析

Abstract

Abstract: 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.

Key words: underground fissure water, coupling action of seepage and rock mass structure, strength and deformation
