成都市天府新区兴隆14路部分苜蓿叶立交设计方案

Design Scheme of Partial Alfalfa-leaf Interchange in Xinglong 14 Road of Tianfu New Area in Chengdu City

兴隆14路部分苜蓿叶立交是联系兴隆湖片区与成都主城的控制性节点之一。根据交通量预测、行人及非机动车出行条件、立交对周边地块的服务条件等因素,项目拟定2个立交竖向设计方案。在综合考虑交通量预测、行人及非机动车出行条件、立交对周边地块的服务条件、工程投资、主线行车条件、地形地貌、地铁、有轨电车等影响因素后,得出推荐方案,可为类似城市互通立交工程设计提供参考。

Xinglong 14 Road Partial Alfalfa-leaf Interchange is one of the control nodes linking Xinglong Lake Area and the main city are of Chengdu.According to the traffic volume forecast,the pedestrian and non-motorized travel conditions,the service conditions of the surrounding land,two vertical design schemes of interchanged are proposed for this project.The scheme is recommended after the comprehensive consideration of traffic volume forecast,the pedestrian and non-motorized travel conditions,the service conditions of the surrounding land,the engineering investment,the main line driving conditions,the terrain features,the subway,the tram and the other factors,which can he referred for the design of the similar urban interchange projects.
