摘要
对中山市北环路节点进行了新建立交的方案研究。该立交为拟建中开高速公路与3条城市高等级道路相交的立交,立交方案设计需考虑收费系统与非收费系统道路的交通转换,也要考虑新增立交对既有立交的影响。根据项目周边限制条件和交通分析,提出了立交方案设计的3种思路和4个代表性的立交方案。对4个立交方案从立交功能、规模、用地、拆迁、适应性及造型等方面进行综合比较和分析,最后提出功能较齐全、规模适中、造型优美、与现状结合较好的建议方案,可为类似的高速公路在城区附近设置互通立交时提供参考。
The article studies the new interchange scheme at a node of North Ring Road in Zhongshan City.This interchange is proposed to intersect an expressway with three urban high-class roads.It is required to consider the traffic conversion of the charge system and non-charge system roads,and also to consider the influence of newly built interchange on the existing interchanges.Based on the surrounding conditions and traffic analysis of the project;the article puts forward three design concepts of interchange scheme and four representative interchange schemes.The article comprehensively compares and analyzes four interchange schemes from the aspects of interchange function,scale,land,removal,adaptation and modeling and finally puts forward the proposed scheme with more complete functions,suitable scale,beautiful modeling and better combination with the status,which can be referred for constructing the interchanges near the urban areas in the similar expressways.
