沪通铁路昆山段建设方案及主要节点方案研究

Research of Kunshan Section Construction Plan and Main Node Research of Shanghai to Nantong Railway

沪通铁路昆山段位于太仓南至安亭区段,该段线路与既有公路、铁路交叉节点较多,为保障沪通铁路施工及既有铁路运营安全,以及满足地方政府要求,有必要对该段线路建设方案及主要节点方案进行深入研究。通过对主要节点进行多方案比选分析和研究,确定沪通铁路昆山段建设方案为上跨天福路后采用700m半径下穿京沪高铁、沪宁城际,上行线采用1-64m下承式钢桁梁上跨京沪铁路,尔后与京沪铁路并行同孔下穿G1501高速公路引入京沪铁路安亭站。

Shanghai to Nantong railway kunshan section is located in Taicang south to Anting segment,and there are more nodes in the segment line and both highway and railway intersection,in order to ensure the security of Shanghai to Nantong railway construction and operation,both the railway safety,and meet the requirements of local government,it is necessary for the segment line construction plan and main node for further research.Based on scheme comparison analysis and research on main nodes,it is determined that the construction scheme of Shanghai to Nantong railway Kunshan section is crossing over Tianfu road with 700 mradius after wearing the Beijing-Shanghai high-speed railway,the Shanghai-Nanjing intercity,is using 1~64mconcrete-filled steel truss overpass and the Beijing-Shanghai railway,then with the Beijing-Shanghai railway parallel hole under crossing G1501 highway into the Beijing-Shanghai railway anting station.
