新建地铁换乘车站对已建车站影响研究

Construction Impact of New Metro Transfer Station on Existing Station

随着上海轨道交通的发展和地下空间的应用,线路间将会形成越来越多的换乘节点。由于换乘线路有时不能同期进行建设,新车站施工会对已运营的车站造成影响,这就涉及到对已建成地铁车站的保护。通过利用有限元方法对换乘节点进行分析,得到不同换乘形式中新车站施工对已建成车站影响的规律,从而选择更加优化的施工方案和保护措施,为将来的换乘节点的施工作必要的技术储备。

With the development of rail transit and underground space,there will be more and more transfer points be- tween the routes.Because of the construction sequence of rail transit stations,the construction of new stations may have impact on the existing station.And by finite element analysis,this paper studies the regulation of such influence in different transfer in order to optimize the construction plan and protection measures and benefit the fu- ture construction.
