地铁明挖车站局部下穿既有建筑物施工技术研究

Research on Construction Technology of Open-cut Subway Station Partially Underpassing Existing Buildings

明挖是地铁车站施工的主要方法之一,在施工过程中有可能会出现下穿既有建筑物的现象,如果仍然使用明挖的方式会增加施工的时间以及成本投入,为此需要对施工工法进行改进,使用暗挖的方式对车站局部进行施工,可以避免破坏原有建筑物。本文分析了地铁明挖车站局部下穿既有建筑物施工技术,以期可以为后续地铁车站施工提供有效参考。

Open-cut is one of the main methods of subway station construction.During the construction process,there may be the phenomenon of underpassing existing buildings.If the open-cut method is still used,it will increase the construction time and cost investment.For this reason,the construction method needs to be improved,and the underground excavation method is used to construct the station part to avoid damage to the original building.This paper analyzes the construction technology of the open-cut subway station partially underpassing the existing building,hoping to provide an effective reference for the subsequent subway station construction.
