| 摘 要： | 地下水对岩体的强度和变形有显著的影响，由于地下裂隙水的渗流作用，岩体强度降低，围岩稳定性减弱。为了有效反映地下裂隙水对大岗山地下洞室群围岩稳定性的影响，根据岩体流固耦合作用机理，采用FLAC3D计算程序对该工程体稳定进行了计算分析。计算结果表明，渗流的作用虽然致使围岩稳定性更加不利，但由于加固措施得当，运行期的洞室群整体已趋于稳定。

| 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. |
