摘　　要：通过三维有限元数值模拟 ,分析了重庆市轻轨小什字车站高层建筑地基下大跨度浅埋洞室K0+ 6 87～K0 + 771段开挖落底前后围岩的应力、位移状态 ,得出了洞室衬砌结构内力的最不利组合和洞室的整体稳定性结论 ,以供设计和施工参考。Through numerical simulation by 3D FEA the stresses and displacement of surrounding rock around the cavern completion excavation at Chongqing Xiaoshizi Rail Station which is located under a high rise building foundation are analyzed herein.The adverse combinations of lining internal force are given and the stability of the cavern is assessed,which can be used for reference to designers and constructors.

关 键 词：重庆 地基洞室 衬砌内力 围岩 稳定性
