城市枢纽立交选型与空间利用关系研究

Research on Planning and Allocation of Urban Pivotal Interchange

城市枢纽立交规模大、线路多、交通组成复杂,其方案选取的合理及空间的充分利用具有重要的实际意义。文章从城市枢纽立交的定位与空间划分出发,通过五处具有代表性的立交方案与空间利用关系的分析,对城市枢纽立交总体方案选取及其空间的集约利用进行了研究,总结了城市枢纽立交构型与空间利用的几种基本模式。

The urban pivot interchange is with large scale, multi-roads and complex traffic flow. It is practical to properly select the general scheme and utilize the space of the interchange. This paper started from the allocation and space division of urban pivot interchange, then, the utilization relation between the general scheme and space utilization are discussed by analyzing the five typical urban pivot interchanges and their space utilization. And, the basic modes of the general scheme and space utilization of urban pivot interchange are generalized.
