武汉市友谊大道北段高架与地铁共线段方案设计

Design of Elevated Expressway and Metro Mutual Section Scheme in North Section of Youyi Avenue in Wuhan

城市交通走廊稀缺,高架快速路与地铁共线不可避免,如何布置高架断面是前期方案设计的重点。首先介绍了武汉市友谊大道北段高架的建设背景、工程概况以及共线段相关地铁的情况;然后结合项目特点,针对共线段提出了两个断面方案,从地铁影响、立交与匝道设置、地面交通组织、环境与景观等方面分析了两个方案的优缺点;最后推荐采用中央绿化带设置桥墩的断面方案。

The urban traffic corridor is scarce,and it is inevitable that the elevated expressway and metro share the same line.How to arrange the elevated cross-section is the key point of the preliminary project design.The construction background,engineering situation,and metro situation at the mutual section of the north elevated expressway of Youyi Avenue in Wuhan are firstly introduced.Then combined with the engineering characteristics,two cross-section schemes are proposed for the mutual section.The advantages and disadvantages of two schemes are analyzed from the aspects of metro influence,interchange and ramp layout,ground traffic organization,environment and landscape.Finally,the cross-section scheme of bridge pier with central green belt is recommended.
