【摘要】：郑州新郑机场至周口西华高速公路是新版《河南省高速公路网调整规划方案》中新增的高速公路规划项目,项目的路线比选、桥梁比选、互通比选、路面的比选等方面是高速公路前期建设需要考虑的问题。选择方案是否科学合理直接影响到项目建成后能否满足国家经济建设需要,决定了本项目是否能达到预期的效果。鉴于东环高速公路在河南省路网中的重要作用,论文基于对国内外高速公路设计中关键性技术问题的研究现状分析,归纳国家及地方高速公路建设的现状与特点:具体阐述东环高速公路初步设计的基本过程,并重点分析东环高速公路初步设计中关键性问题的解决方法进而多方面对高速公路初步设计关键技术理论进行研究。论文首先对课题的来源、意义和国内外研究进行了介绍;其次,对区域高速公路发展现状与特点进行说明,明确本项目的重要地位;其三,阐述航空港经济综合实验区东环高速公路的总体设计以及路基路面及排水设计、桥涵设计和交叉的初步设计;第四,对东环高速公路的关键技术进行了重点研究,着重进行了推荐线和比较线进行了比较,进而对沿线大型桥梁的初步设计,沿线5个互通式立交的初步设计进行了充分的分析研究。最后,对项目进行了归纳总结,进一步深化研究内容和亟待解决的问题。
[Abstract]:Zhengzhou Xinzheng Airport to Zhoukou Xihua Expressway is a newly added highway planning project in the new edition of Henan Province Highway Network Adjustment Plan. The route of the project is compared and selected, the bridge is compared, and the interchange is compared. The comparison and selection of pavement are the problems to be considered in the early construction of expressway. Whether the project is scientific, reasonable or not will directly affect whether the project can meet the needs of national economic construction or not, which determines whether the project can achieve the expected results. In view of the important role of Donghuan Expressway in the road network of Henan Province, this paper based on the analysis of the research status of the key technical problems in highway design at home and abroad. The present situation and characteristics of national and local highway construction are summarized. The basic process of preliminary design of Donghuan Expressway is elaborated in detail. The key problems in the preliminary design of Donghuan Expressway are analyzed and the key technology theory of the preliminary design of Donghuan Expressway is studied in many aspects. Firstly, this paper introduces the origin, significance and domestic and international research of the project, secondly, explains the current situation and characteristics of the regional highway development, and clarifies the important position of the project. Thirdly, the general design of Donghuan Expressway, the design of subgrade and pavement and drainage, the design of bridge and culvert and the preliminary design of crossing are expounded. Fourthly, the key technology of Donghuan Expressway is studied, and the recommended and comparative lines are compared, and then the preliminary design of large bridges along the route is given. The preliminary design of 5 interchanges along the route has been fully analyzed and studied. Finally, the project is summarized to further deepen the research content and problems to be solved.
