城市互通立交选型要点及对策研究

摘要:

随着城市化进程的进一步发展,城市道路互通设置在空间尺度、功能要求、立交形式及工程规模方面的分析越来越重要。该文以城市建成区快速路-机场高速节点立交工程为研究背景,对立交方案选型及影响因素进行综合论证分析,研究城市建成区工程边界条件,考虑立交节点工程周边工程特征,地质特点等影响,通过多方案比选论证,分析城市建成区立交设计难点,提出城市互通立交选型要点及对策。成果可为城市建成区立交设计及选型提供依据和参考。

Abstract:

With the further development of urbanization, the analysis of urban road interconnection settings in terms of spatial scale, functional requirements, overpass forms, and project scale becomes more and more important. This article takes the urban built-up area expressway-airport expressway node interchange project as the research background, comprehensively demonstrates and analyzes the selection of the interchange scheme and its influencing factors, studies the boundary conditions of the urban built-up area engineering, and considers the engineering characteristics and geological characteristics of the interchange node project. Influence, through the multi-scheme comparison and selection, analyze the difficulties in the design of urban built-up interchanges, and put forward the key points and countermeasures for the selection of urban interchanges. The results can provide a basis and reference for the design and selection of urban interchanges in built-up areas.
