以北京地铁五号线北新桥站作为实例,分析了工程周边的环境,明确了工程的难点,并重点阐述了交通导流措施中最重要的部分———便桥的设计与施工,还讨论了管线保护的问题,最后分析了施工监控量测结果,以此为例浅谈了在城市复杂环境地铁车站深基坑施工技术问题。 Taking Beixinqiao Station of Beijing Subway Line 5 as an example, the surrounding environment of the project is analyzed, the difficulties of the project are clarified, and the most important part of the traffic diversion measures --- the design and construction of the convenient bridge is also discussed Pipeline protection, and finally analyzes the results of construction monitoring measurements. Taking this as an example, the technical problems of deep foundation pit construction in metro stations with complicated urban environment are briefly discussed.
