某高速公路终点枢纽互通方案比选过程

Comparison and Selection Process of an Expressway Terminal Junction Interchange Scheme

随着我国现代化进程的推进,公路交通得到了迅速发展。目前,高速公路构筑起来的国家路网骨架已基本形成,设计建设重心也逐渐转移至路网加密工程。公路之间的节点设计以及既有节点改造等成为常态。论文通过实际工程设计案例来说明路网加密中节点设计的关键技术问题、方案研究过程,为类似工程提供借鉴作用。

With the advancement of China's modernization process,highway traffic has been rapidly developed.At present,the framework of the national highway network has been basically formed,and the focus of design and construction has gradually shifted to the network encryption project.The design of nodes between highways and the reconstruction of existing nodes have become normal.In this paper,the key technical problems and the research process of the project in the network encryption node design are explained through the practical engineering design cases,which can provide reference for similar projects.
