铁路因素影响下枢纽式互通立交位置选择及方案设计研究

Research on the Location Selection and Scheme Design of Hub Interchanges under the Influence of Railway Factors

连云港至宿迁高速公路是江苏省高网规划中新增的“横三”线,作为新建高速公路,沿线与沈海高速公路交叉并设置灌云东枢纽实现交通转换。在项目区域内,连盐铁路与沈海高速公路近距离平行,因此结合灌云东枢纽,分析了在铁路因素影响下枢纽式互通立交的位置选择,结合不同位置的预测交通量及周边环境对互通立交的影响进行选型布线,研究比对了不同互通方案的优缺点,得出最优设计方案,以期为类似项目提供参考。

Lianyungang-Suqian expressway is a new "Hengsan" line in the high-speed network planning of Jiangsu province.As a new expressway,the region near the line crosses with Shenhai expressway and sets Guanyun east hub to realize traffic conversion.In the project area,Lianyan railway and Shenhaiexpressway are close and parallel.Therefore,in combination with Guanyun east hub,the location selection of hub interchange under the influence of railway factors is analyzed.Based on the predicted traffic volume at different locations and the influence of the surrounding environment on interchanges,the selection and arrangement of wires are carried out.The advantages and disadvantages of different interchanges are studied and compared,and the optimal design scheme is obtained,so as to provide reference for similar projects.
