地铁十字交叉换乘车站全暗挖同步建造技术

Simultaneous Mining Construction Technology for Cross Interchange Subway Stations

从北京地铁黄庄站工程特点及建设条件影响分析入手,阐明采用全暗挖法技术在复杂环境条件下同步建造十字换乘车站的必要性,并就一次扣拱暗挖逆作法、暗挖交叉节点结构形式、暗挖进洞、环境保护及风险控制等暗挖关键技术进行阐述。

In the paper,through analyzing the features and construction conditions of Huangzhuang Station project on Beijing subway,the need for simultaneous construction of the metro station under complex environmental conditions by full tunneling method is illustrated. The key technologies for underground construction are explained,including top-down excavation with one-step casted arch,mining excavation with cross joint structure,mining excavation to enter into the station main tunnel as well as environment protection and risk control.
