［摘要］ 地鐵春熙路站基坑地處成都市區(qū)繁華地段，其周邊地上建筑、地下構筑物密集。針對周邊環(huán)境介紹了復雜環(huán)境下基坑圍護結構的設計思路，并重點介紹了圍護結構與相鄰的紅星路下穿隧道協(xié)同受力的設計分析方法。利用ANSYS軟件及APDL參數(shù)化設計語言模擬鄰近紅星路下穿隧道側圍護結構的基坑開挖、回筑過程，結構分析結果與監(jiān)測數(shù)據(jù)基本吻合，可供類似工程設計參考。

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
