摘要
以郑州市城市经济发展、总体规划和要求为前提,以郑州市城市交通规划为依据,吸取国内外快速路建设过程中的经验和教训,结合实际情况,提出了"主线保留现状地面道路,在沿线主要横向道路通过设置互通立交,次要横向道路设置跨线桥(或地道)的形式全面实现东四环的快速化"的建设思路,重点研究了3处互通立交的节点方案;论证了工程的技术标准及建设规模,提出了总体布置方案,对立交节点方案进行了较详细的论述。
Based on the economic development, overall planning and requirements of Zhengzhou City,according to the urban transport planning of Zhengzhou, to absorb the experience and lessons in the construction process of expressways at home and abroad, and combined with the practical situation, the construction thoughts of reserving the present ground roads in the main line, constructing the interchanges in the main crosswise roads and setting up the overpasses(or subway) in the secondary crosswise roads along the line are proposed in order to entirely realize the rapid technology of East Ring Ⅳ. The article studies the node schemes of three interchanges, demonstrates the technical standard and construction scale of the project, puts forward the overall layout scheme, and discusses the schemes of interchange node.
