高速公路互通式立体交叉设计研究

Research on Interchange Design of Expressway

互通立交是将高速公路连接为高速公路网络的关键性节点工程,是高速公路工程建设中不可或缺的重要组成部分。论文对互通式立体交叉设计开展了研究,对互通式立体交叉设计的位置步骤进行了分析,探讨了互通式立体交叉的基本形式及选择原则,并对立交设计的交通功能及评价指标进行了分析,以期改善高速公路互通立交的建设水平。

Interchange is the key node project connecting expressway to expressway network,and it is an indispensable and important part of expressway construction.This paper studies the design of interchange,analyses the location and steps of interchange design,discusses the basic form and selection principle of interchange,and analyses the traffic function and evaluation index of interchange design in order to improve the construction level ofExpressway interchange.
