互通立交设计中的典型问题分析及对策

ANALYSIS AND COUNTERMEASURES OF TYPICAL PROBLEMS IN INTERCHANGE DESIGN

随着我国城镇化的不断推进,中心城市及副中心城市的交通越来越繁忙,城市中出现了较多的快速路,城市周边交通成环,涉及快速路和高速公路等高等级道路的交叉数量不断增多。在这些交叉的设置中,互通式立体交叉成为很多节点的首选解决方案,但在互通立交的设计过程中存在诸多典型问题亟待解决。就互通立交设计过程中常见的典型问题予以分析,并着重探讨对策,以利于开阔互通立交设计人员的设计思路,提高互通设计从业者解决问题的基本能力。

With the continuous improvement of China’s urbanization, the traffic in central and sub central cities is getting busier and busier. There are more expressways in the city. The traffic around the city is in a ring, and the number of intersections involving expressways, expressways and other high-grade roads is increasing. In the setting of these intersections, interchange has become the preferred solution for many nodes, but there are many typical problems to be solved in the design process of interchange. The paper focuses on the analysis of common typical problems in the process of interchange design, and focuses on the countermeasures, so as to broaden the design ideas of interchange designers and improve the basic ability of interchange design practitioners to solve problems.
