郑州市西四环-渠南路城市互通立交方案设计

Design of Zhengzhou West Fourth Ring-Qunan Road Urban Interchange

目前,随着城市规模不断发展,汽车保有量不断增长,交通拥堵成为城市管理中的突出问题亟待解决。互通立交作为城市疏缓交通拥堵的重要方式,可以提高交叉口的通行能力,因此,有必要对城市互通立交设计方案进行研究。以郑州市西四环-渠南路立交为例,首先分析了互通立交设计的原则和步骤,然后结合工程实践,具体分析了郑州市西四环-渠南路立交设计方案。

At present,with the continuous development of urban scale and the growth of car ownership,traffic congestion has become a prominent problem in urban management to be solved urgently.As an important way to alleviate traffic congestion in the city,interchange can improve the capacity of intersections.Therefore,it is necessary to study the design scheme of urban interchange.Taking zhengzhou West Fourth Ring road to Quannan Road interchange as an example,this paper firstly analyzes the design principles and steps of the interchange,and then analyzes the design scheme of Zhengzhou West fourth Ring road to Quannan Road interchange based on engineering practice.
