摘要: 建立了同时考虑基坑围护结构、土体与地下管线变形耦合作用的三维有限元分析模型 ,对地下管线保护措施的几种方法进行了数值分析 ,得出了对设计、施工有一定指导意义的结论。Abstract: Based on the previous study, the coupled action of the retaining structu re, soil and pipeline is considered. All kinds of pipeline protections are analy zed by numerical simulation. The results which are important to guide design and construction, are obtained in this paper.
