摘要
随着社会经济、路网的发展,原已建成的高速公路部分面临着改建、扩建的需要,而作为高速公路重要组成部分的互通式立体交叉常常成了改扩建工程设计中的关键和难点。文中通过厦蓉线适中-莒舟互通立交改扩建工程探讨了高速公路中互通立交扩建方案设计的技术思路和基本原则。
With the development of economic and road network,some express highways which have been built are now facing the need to renovated or expanded.As an important part of Expressway,the expansion design of interchange is often the key and the most difficult point.Taking the Shizhong to Juzhou interchange expansion project of Xiamen-Chengdu highway as an example,this paper discussed the design techniques and basic principles of interchange expansion in express highways.
