快速城市化地区高速公路城市化改造关键技术问题研究

Study on Key Technical Problems of Expressway Urbanization Reconstruction in Rapid Urbanization Region

介绍了城市化进程中高速公路与城市用地之间的功能演变关系。结合国内外高度城市化地区相关案例,系统分析这种功能演变对城市发展所带来的影响。针对这种城市化进程后期出现的高速公路穿越城市核心区的矛盾,从用地发展、路网功能、建设条件等角度,提出合理的改造模式,继而确定技术标准。重点对高速公路城市化改造中的技术方案要点进行详细论述,为未来城市发展中高速公路城市化改造规划建设提供参考。

This paper introduces the functional evolution relationship between the expressway and urban land use in the urbanization process. Combined with the relative cases of high urbanization regions at home and abroad, this paper systematically analyzes the influence of this functional evolution on the urban development. Aiming at the contradiction of expressway through urban core emerging in the later period ofthis urbanization process, this paper puts forward the reasonable reconstruction mode from angle of land development, road network function and construction conditions, and then determines the technical standards.This paper discusses the essentials of technical scheme in the expressway urbanization reconstruction in detail in order to provide the reference for the expressway urbanization reconstruction, planning and construction in the future urban development.
