临沂市沂河快速路滨河互通立交节点方案研究

Study on Reconstruction Scheme of the Riverside Interchanges of Yihe Expressway in Linyi

沂河路滨河立交节点是沂河路快速化改造工程的关键节点,对于推动城市快速环线的贯通进程、完善快速路网、提升交通出行效率具有重要意义。针对滨河立交节点现状存在的问题进行分析,基于沂河路与沿河道路的功能定位和交通需求,提出蝶形全互通方案及双环扣立交方案。在方案比选的基础上,因地制宜,优化立交形态和交通组织,保障交通转换功能,提升景观协调性,降低环境影响,对于跨河交通节点及滨水道路的建设具有较高的参考价值。

The riverside interchanges on both sides of the Yihe river are key nodes of Yihe Expressway,which is significant to promote the completion of the ring expressway and improve the urban expressway system to provide residents convenience.Problems existing in current riversides interchanges are analyzed herein and the schemes of full butterfly interchange and double-ring interchange are proposed based on the functional orientation and traffic demand of Yihe expressway and the riversides roads.On the basis of scheme comparison,the interchange form and traffic organization are optimized according to local conditions,considering the transfer function,the landscape coordination and the environmental impact of the interchanges,which may provide a good reference for the construction of riversides roads and intersections on bridgeheads.
