南京枢纽新建过江通道对枢纽运输布局的影响

Impact of Newly-built Channel Crossing Yangtze River on the Transportation Layout of Hubs in Nanjing Junction

南京铁路枢纽位于南京市长江两岸,共有8条干线引入。为衔接6个方向的路网性放射式环型铁路枢纽,文章结合南京铁路枢纽规划,对枢纽内既有过江通道进行客、货运量预测,然后从各个角度对南京枢纽内新建上元门隧道过江通道及七乡河大桥过江通道两个方案进行对比研究,最终推荐新建上元门隧道过江方案。

The Nanjing railway junction is located on both banks of the Yangtze River in Nanjing,in total 8 trunk lines are introduced,is a road network radial ring-shaped railway hub connecting 6 directions.Combined with the planning of the Nanjing Railway Junction,and passenger and freight volume forecast on the existing river crossing channel in the hub,this paper compares the two schemes of the newly constructed Shangyuanmen Tunnel river crossing channel and Qixianghe Bridge river crossing channel in the Nanjing railway junction.Finally,the proposal of new Shangyuanmen tunnel crossing the river is recommended.
