［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(gòu)筑物密集。針對周邊環(huán)境介紹了復(fù)雜環(huán)境下基坑圍護(hù)結(jié)構(gòu)的設(shè)計(jì)思路，并重點(diǎn)介紹了圍護(hù)結(jié)構(gòu)與相鄰的紅星路下穿隧道協(xié)同受力的設(shè)計(jì)分析方法。利用ANSYS軟件及APDL參數(shù)化設(shè)計(jì)語言模擬鄰近紅星路下穿隧道側(cè)圍護(hù)結(jié)構(gòu)的基坑開挖、回筑過程，結(jié)構(gòu)分析結(jié)果與監(jiān)測數(shù)據(jù)基本吻合，可供類似工程設(shè)計(jì)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
