黄阁东互通方案探讨

Discussions on Design Scheme of the Huangge East Interchange

复合通道与市政道路及高速公路交叉时设置的互通立交,需考虑复合通道上下层的功能定位、被交路的交通需求、交通量预测、建设条件、用地和工程造价等综合因素。黄阁东互通为了实现造型美观、匝道转向通行效率高、立交层次分明的目的,结合交叉道路之间的交叉形式,提出多种互通方案进行比选分析,最终确定将涡轮形枢纽互通作为推荐方案,为其他类似复合通道互通方案的设计提供参考。

The interchange scheme between the composite channel and municipal roads and expressways should take into account the functional positioning of the upper and lower levels of the composite channel,the traffic demand of the intersected roads,the traffic volume forecast,the natural conditions,the land utilization and the project cost,as well as other comprehensive factors.In this paper,the interchange scheme in the paper adopts a turbine-shaped hub interchange with grace appearance,high efficiency of ramp turning and distinct interchange levels.According to the intersection form between the road crossings,multiple interchange schemes are proposed for comparison and analysis,and the recommended scheme is finally determined,which provides a reference for the design of other similar composite channel interchange schemes.
