洪都大道快速化改造工程方案研究

Study on the Scheme of Hongdu Avenue Rapid Reconstruction Project

洪都大道是南昌市骨架路网的重要组成部分,针对其交通拥堵,老火车站的客流无法集散的现状,对洪都大道快速路总体方案、节点方案和桥型结构进行研究,并结合路网规划和现状条件,道路段选用“主线高架+地面辅路”的布置形式,桥梁段选用预制节段大箱梁和部分桥墩预制装配化,建设完成后将实现南昌市内环线的闭合,发挥骨架路网在城市交通中的作用。

Hongdu Avenue is an important part of the skeleton road network of Nanchang City.In view of its traffic congestion and the inability of the old railway station to collect and distribute passenger flow,the overall scheme,node scheme and bridge type structure of Hongdu Avenue Expressway are studied.In combination with the road network planning and current conditions,the layout of“main line elevated+ground auxiliary road”is selected for the road section,and prefabricated segmental large box girders and some piers are selected for the bridge section,After the completion of the construction,the inner ring road of Nanchang will be closed,giving play to the role of the skeleton road network in urban traffic.
