摘要
软土地区邻近地铁运营线路的深大基坑开挖是一项极其复杂的工程。基坑开挖过程中,如何保证地铁隧道的稳定和安全是整个工程中必须考虑的问题。通过同类工程实测反分析的设计施工参数,应用三维有限元分析手段,预估分析基坑开挖对紧邻地铁隧道的影响,探讨减少基坑开挖对紧邻地铁隧道影响的控制措施,以保证地铁的正常运营,为类似工程设计与施工提供借鉴和参考。
The excavation of deep-large-foundation pit near metro line is very complex, how to guarantee the stability and safety of metro tunnel is the first consideration during the excavation. With the measured date and feedback analytic parameters of the similar project design and construction, this paper uses the finite element method to analyse the influence of deep foundation pit on nearby metro tunnel, and discusses the control measures to reduce the influence and guarantee the normal operation of subway.
