南宁市英华路-青山路立交方案研究

Study on Scheme of Yinghua Road-Qingshan Road Interchange in Nanning

南宁市英华路-青山路立交位于快速路与主干路交叉口,项目周边用地受限,建筑物密集,建设难度大。根据2条被交道路一凹一凸的特点,提出了3层菱形立交方案,通过隧道分离南北向直行交通,跨线桥分离东西向直行交通,转向交通均在地面层完成的方式,较好地实现了路口立交化。同时通过加长南北向隧道框架段长度,在凤岭南路设置下穿隧道的方式,解决了项目周边2个重要出入口的交通问题。

Yinghua Road-Qingshan Road Interchange is located at the intersection of the expressway and major road in Nanning.The land around the project is limited,the buildings are dense and the construction is difficult.According to the characteristics of two intersected roads with one concave and one convex,a three-layer diamond interchange scheme is proposed.Through the way of separating the north-south straight traffic in the tunnel,separating the east-west straight traffic by the overpass bridge,and completing the turning traffic at the ground level,the intersection interchange is better realized.At the same time,by lengthening the length of the north-south tunnel frame section and setting the underpass tunnel in South Fengling Road,the traffic problems of two important entrances and exits around the project are solved.
