摘要
北京地铁六号线二期工程起点至物资学院站区间平交段为大截面暗挖施工,其主要工序包括大管棚超前支护、双侧壁导坑法开挖支护、拱部深孔注浆加固等,针对施工难度高、风险大等特点,制订了合理的施工工艺,控制了施工风险。
Large-section mining excavation method is adopted at the plane crossing segment between the starting station and Wuzi University Station of Beijing Subway Line 6 Phase Ⅱ.The main construction steps include advance support of large tube shelter,support for excavation by double side-wall pilot tunnel method and grouting reinforcement of deep holes on arch,etc.Considering difficult construction and high risk,appropriate construction processes are established to control the construction risks.
