摘要

采用三维有限差分FLAC3D程序，以二滩工程地下洞群的结构形式为背景，提出interface界面模型模拟断续节理的力学效应，考虑与不考虑节理岩体静水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。通过系统分析得出相应的结论，为大型地下工程围岩稳定分析提供了有益的参考。

Abstract

The FLAC3D, which is a threedimensional explicit finitedifference software, is used to perform the numerical simulation in the underground caverns of Ertan Project in this paper. An interface model is established to simulate intermittent joint effect. The threedimensional seepage which has influence on the stability of the surrounding rock is calculated. Some conclusions are drawn, which can provide some useful reference for the study of largescale underground caverns.

Key words： ; joint seepage interface model systematic analysis stability of surrounding rock
