摘　　要：采用三维有限差分FLAC3D程序,以二滩工程地下洞群为背景,考虑断续节理是影响地下洞室围岩稳定的重要因素,为有效反映其影响,本文提出Interface界面模型模拟断续节理的力学效应,对考虑与不考虑节理岩体渗流对围岩稳定性进行了大量计算工况的准三维数值模拟。得到相应的结论,可供大型地下洞室群稳定分析时作为参考。FLAC^3D was used to carry out simulation analysis in underground power house of Ertan Project in this paper. FLAC^3D is a three dimensional explicit finite-difference program. Intermittent joints are important factors affecting stability of surrounding rockmass. In order to reflect their action, an interface model is established to simulate intermittent joint effect. By considering the seepage factor which influence the stability of wall rocks lots of numerical simulation analysis with approximate three dimension were done. Some disciplinarian conclusions were drawn from the systematic analysis. These conclusions will provide some useful reference for the study of large-scale underground cavern groups.
