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。
Subway Chunxi Road Station pit is located in the bustling area of Chengdu City, the surrounding ground buildings, underground structures dense. The design idea of the foundation pit supporting structure in complicated environment is introduced in view of the surrounding environment. The design and analysis method of the cooperative force between the retaining structure and the adjacent tunnel beneath Hongxing Road is emphatically introduced. Using ANSYS software and APDL parametric design language to simulate the excavation and backfilling process of the foundation pit under the tunnel near the Red Star Road, the structural analysis results are in good agreement with the monitoring data, which can be used as a reference for similar projects.
