安阳至新乡高速公路辉县南互通立交方案设计研究

Research on Huixian South Interchange of Anyang to Xinxiang Expressway

以安阳至新乡高速公路鹤壁至新乡段终点辉县南互通为研究对象,从互通满足交通功能出发,结合周边现状高速、村落、高压线等控制因素,提出了3个方案,分别从占地、工程造价、施工难易程度进行比较,最终选定方案一作为推荐方案。方案一与现状辉县南互通组合成复合式互通形式,既能解决安新高速与其他高速之间车流转换和实现服务周边镇区功能,又能避免安新高速与菏宝高速、郑辉高速之间形成5路交叉增加工程造价和工程占地的问题。从另一个角度解决多条高速之间交通转换问题,能够为其他类似项目提供参考。

In the paper,the Huixian South Interchange at the ending point of the Hebi to Xinxiang Section of Anyang to Xinxiang Expressway(An-Xin Expressway)is taken as the study object.From the perspective of mutual communication to meet the traffic function,combined with the surrounding status of expressways,villages,high-voltage lines and other control factors,three schemes are proposed.Comparisons are carried out respectively from the land occupation area,project cost,construction difficulty,and finally Scheme 1is selected as the recommended scheme.Scheme 1combines the existing Huixian South Interchange into a composite interchange,which can not only solve the functions of traffic conversion between An-Xin Expressway and other expressways but also realize the functions of serving the surrounding towns.Scheme 1can also avoid the formation of a five way hub interchange between An-Xin Expressway,Heze-Baoji Expressway and Zhengzhou-Huixian Expressway to increase project cost and land occupation.The paper solves the traffic conversion problem among multiple expressways from another perspective,which can provide reference for other similar projects.
