南京滨江大道快速路组合式菱形立交方案研究

A Study of Binjiang Ave.Expressway Combined Diamond Interchange Plan in Nanjing

依据南京滨江大道(南段)设计理念,根据滨江大道路网结合路段流量分析,在城市快速路建设标准下,重点论述立交方案选型。基于其承担较多的过境交通,又位于长江江边,转向交通量存在着较大的不均匀性,故采用组合式菱形立交方案。具体设计方案取用长距离下沉式道路。最后还重点讨论了菱形立交匝道夹角角度的控制。

According to the design idea of Nanjing Binjiang Ave.(south section) and the traffic flow analysis of linked roads of Binjiang Ave.roadnet,the interchange plan selection is presented in this paper with emphasis under the standard of urban expressway construction.Due to the interchange bearing heavy through traffic,its special location(located by Yangtze River) and large nonuniformity of traffic flow,the combined diamond interchange plan is chosen finally.The specific design plan is adopting long-distance sunk road.Moreover,the ramp's included angle control is discussed by the author.
