明挖车站跨路口局部盖挖逆作法施工技术研究

Research on Construction Technology of Cut-cover Top-down Excavation Method for Road Crossing Section of Open-cut Subway Station

为减少地铁车站明挖法施工阻断交通的时间,降低对周边道路的影响,提出明挖法车站局部盖挖逆作工法。依托长春地铁6号线蔚山路站工程,对明挖车站跨路口局部盖挖逆作法施工技术和施工流程进行详细阐述。实践表明,明挖车站局部盖挖逆作法能最大程度优化成本和工期,同时降低对周边交通的影响,可为类似工程提供借鉴参考。

In order to reduce the time of blocking the traffic and reduce the influence on the surrounding roads,this paper puts forward the cut-cover top-down excavation method for partial section of the open-cut subway station.Based on the Weishan Road Station project of Changchun Metro Line 6,the construction technology and construction process of the cut-cover top-down excavation method for road crossing section of the open-cut subway station are expounded in detail.The practice shows that the cut-cover top-down excavation method for partial section of the open-cut subway station can optimize the cost and construction period to the greatest extent,and reduce the impact on the surrounding traffic,which can provide reference for similar projects.
