［摘要］   地铁春熙路站基坑地处成都市区繁华地段，其周边地上建筑、地下构筑物密集。针对周边环境介绍了复杂环境下基坑围护结构的设计思路，并重点介绍了围护结构与相邻的红星路下穿隧道协同受力的设计分析方法。利用ANSYS软件及APDL参数化设计语言模拟邻近红星路下穿隧道侧围护结构的基坑开挖、回筑过程，结构分析结果与监测数据基本吻合，可供类似工程设计参考。

Abstract:Chunxi Road Station，encircled by crowded buildings，is located in the downtown district of Chengdu. The design of bracing structure under complex surroundings situation was introduced, especially the structural analysis of the bracing structure near Hongxing tunnel was focused on. The digging and re-construction process were simulated by ANSYS program and the simulation results agreed with the monitoring data. It can be used as a reference to similar projects.
Keywords:deep foundation pit; bracing structure; complex surroundings; coordination action; structural analysis
