摘要
结合北京地铁光华路车站侧洞的施工实践，介绍了采用CRD工法施工的浅埋暗挖隧道，在进行二次衬砌施工时的流水段划分、临时初支拆除、全包式分区防水、模注混凝土等关键技术，以保证施工安全。
Taking the construction practice in the side drift of Guanghua Road station of Beijing metro as an example, this paper introduces the key technologies on construction section division, temporary shoring demolision, wholly-covering-zoning waterproof and concrete placing, etc. When the secondary lining is carried in construction adopted CRD method of shallow-depth-excavation tunnel in order to improve safety in construction.
