在城市建筑物密集、交通拥挤地区修建地铁,盖挖是首选施工方法。在盖挖施工过程中,维护基坑稳定和施工安全,控制周边地层、建筑和管线沉降是施工的关键,这对基坑围护结构及盖板承力结构有很高的要求。就武汉某盖挖逆作车站详细阐述了盖挖车站支护结构设计与施工技术措施,重点介绍了钢管柱与基桩接口施工技术措施。
Construction of metro in densely populated urban areas, congested areas, dredging is the preferred method of construction. In the process of cover excavation, the stability of foundation pit and the construction safety are maintained. The control of the surrounding strata, the settlement of buildings and pipelines is the key to the construction. This has high requirements for the retaining structure of the foundation pit and the bearing structure of the cover. This paper elaborates the design and construction technical measures for the support structure of the dredging station with a cover digging against the railway station in Wuhan. The construction measures of the interface between the steel pipe column and the foundation piles are emphatically introduced.
