摘要
武汉市光谷大道南延线主线高架桥标准宽度26 m,双向6车道设计。高架桥与地铁2号南延线有1.4 km共线段,地铁区间及站点布置对桥梁总体设计影响很大。沿桥梁走向同时分布有2排中高压燃气管道,对桥梁侧边基础布置也有较大影响。桥梁在地铁共线段下部结构采用地梁桩基结构,上部结构采用钢箱梁结构。
The standard width of the main line viaduct of the south extension of Guanggu Avenue in Wuhan is 26 m with the double-way six-lane design. There is a 1.4-km collinear segment between the viaduct and the south extension of Metro Line 2. The metro interval and station layout have a great influence on the overall design of the viaduct. There are two rows of medium and high pressure gas pipelines along the viaduct,which also have a great influence on the layout of foundations at the sides of viaduct. The substructure of the viaduct in the collinear segment of the metro adopts the ground beam pile foundation structure, and the superstructure adopts the steel box girder structure.
