| 摘 要： | 地下洞室群的开挖顺序是影响洞室围岩稳定性的主要因素之一.结合拟建双江口水电站厂区地形地质条件及洞室群结构特点,采用三维弹塑性有限元法,研究不同开挖工序下洞室群围岩的应力场、位移场及破坏区分布规律,对围岩的稳定性进行分析,并以开挖过程中对周围岩体的扰动破坏体积最小、应力集中程度最小、最大位移最小作为优化准则,提出了较优的...

| Abstract: | Construction sequence is one of the major factors affecting the stability of large underground caverns.In light of topographic and geological conditions as well as design features of caverns,3D elasto-plastic FEM is applied to study the distribution laws of stress,displacement and damage zones under different construction sequences,and to analyze the stability of surrounding rocks.By the optimization criterion of the minimum volume of damage zone,minimum stress concentration and minimum displacement,a reaso... |
