| 摘 要： | 断续节理是影响地下洞室围岩稳定的重要因素，要有效反映其影响提出Interface界面模型模拟断续节理的力学效应。以二滩水电工程大型地下洞室群为背景，对主厂房开挖考虑与不考虑断续节理作用进行了多种地应力工况的数值计算与分析，获得了主厂房洞周在断续节理影响下的位移场和塑性区分布规律，为大型地下工程围岩稳定分析提供了有益的参考。

| Abstract: | Intermittent joints are important factors affecting stability of surrounding rockmass. In order to reflect their influence, based on large-sized underground chambers of Ertan Hydropower Project, an interface model is established to simulate mechanical effect of intermittent joints. Taking into account intermittent joint action or not, we have carried out numerical computation analysis for the main opening under various geostress and got some changing laws of displacement field and plastic zone around opening, which provide some useful reference for stability analysis of large sized underground engineering. |

| Keywords: | intermittent joint interface model stability of surrounding rockmass numerical computation |
