摘要

选取水布垭枢纽中部厂房设计方案的地下厂房区域，采用三维弹塑性有限元法，模拟施工开挖过程，研究了复杂地质条件下洞室群围岩的开挖变形形态与应力状态，分析了围岩塑性区分布及地下厂房洞室群围岩的稳定性，最后提出了设计与施工建议。

Abstract

In this paper, the construction and excavation process of underground plant of the Shuibuya Project are simulated by 3D elastoplastic FEM. The excavating deformation pattern and stress state of the chamber group surrounding rock under complex geological conditions are researched .The distribution of plastic areas and stability of surrounding rock is analysed. Finally some suggestions for design and construction are given.
