摘要
近年来,随着我国高速公路快速发展,路网日益密集,城镇等关键节点处互通立交间距较小,难以满足相关规范最小净距要求,需根据工程实际情况设置不同形式的复合式互通立交。以漳县黄土坡枢纽立交工程实例为依托,对复合式枢纽立交在项目研究前期设计思路进行探讨。
In recent years,with the rapid development of Expressways in China and the increasingly dense road network,the interchanges at key nodes such as towns and cities have a small distance,which is difficult to meet the minimum net distance requirements of relevant specifications.Therefore,different forms of compound interchanges should be set up according to the actual situation of the project.Based on the example of Zhangxian Huangtupo junction interchange project,this paper discusses the design idea of compound junction interchange in the preliminary stage of project research.
