与逆作法地铁车站合建的城市景观桥工程设计研究

Study on the engineering design of urban landscape bridge combined with reverse construction subway station

城市轨道交通能有效解决市区出行导致的交通拥堵。为尽量减少南通地铁2号线易家桥站建设对名胜古迹的影响,采用逆作法分区域施工,参考国内外工程案例,逆作法地铁车站与城市景观桥同步实施的案例较少。文章以市政桥梁易家桥为例,介绍城市桥梁和逆作法车站合建的一种成功经验,本次易家桥站建设根据总体方案,桥站的连接部位采用分离式,该经验可为类似项目的进一步研究提供参考。

Urban rail transit can effectively solve the traffic congestion caused by urban travel.In order to minimize the impact on scenic spots and historic sites,the construction of Yijiaqiao station of Nantong Metro Line 2 adopts the reverse construction method in different areas.With reference to the engineering cases at home and abroad,there are few cases of synchronous implementation of reverse construction subway station and urban landscape bridge.According to the overall scheme,Taking Yijia bridge,a municipal bridge as an example,the author introduces a successful experience of joint construction of urban bridge and reverse construction station,which can provide reference for further research of similar projects.
