用地严重受限条件下的立交设计案例分析

Case Study of Interchange Design under the Condition of Severe Restricted Land Use

在城市中心区,因城市道路快速化改造而设置的立体交叉,一般具有用地条件受限的特点。以武汉市常青路复兴立交为例,在交通节点的功能定位、建设条件和流量预测分析的基础上,阐述立交选型设计比较过程,展示立交运行使用效果,总结在用地受限条件下的设计指导思想。分析过程及结论对城区互通立交设计有一定借鉴意义和参考价值。

In the central area of the city,the interchange set up due to the rapid transformation of urban roads generally has the characteristics of limited land conditions.Taking Fuxing Interchange on Changqing Rd.in Wuhan as an example,based on the functional positioning,construction conditions&flow prediction analysis of traffic nodes,it expounds the comparison process of interchange type selection design,shows the operation and use effect of interchange,and summarizes the design guiding ideology under the condition of land restriction.The analysis process&conclusion have certain reference significance and reference value for the design of urban interchange.
