与地铁地下车站合建的桥梁设计

工程采用地铁地下车站和跨线桥梁合建的形式,跨线桥在地铁车站范围内以车站结构作为其下部基础,在盾构区间采用桩基承台基础,设计精心考虑各区间桥梁上下部结构方案,取得了较好的实施效果,站桥合建方案有效节约了建设用地,降低了建设费用,可供类似市政工程参考、借鉴.

Design of Bridge Co-built with Metro Underground Station

The co-build form of underground subway station and overpass bridge is used in a project. The station structure is taken as the lower foundation of the overpass bridge within the scope of subway station. The base slab foundation of pile foundation is used in shield area. The superstructure and substructure scheme of bridge in each area is carefully considered in the design. The good implementation effect is achieved. The co-build scheme of station and bridge can effectively save the construction land and reduce the construction cost, which can be referred for the similar municipal projects.
