摘要
为缓解城市桥梁建设交通压力,节约工期,采用预制节段单室箱梁进行现场组合拼装成跨,代替传统的T形梁、小箱梁架设,通过节段胶接和体内体外预应力分批张拉,形成整跨箱梁及整联连续桥梁,并解决箱梁横向纵向受力问题,是桥梁发展进行装配式施工的新型模式。
In order to alleviate traf?c pressure and save time for construction of urban bridges,prefabricated segmental singlecompartment box girders are used to assemble the span on site instead of traditional T-beams and small box girders,and the whole span box girders and continuous bridges are formed by segmental bonding and internal and external prestressing tension in batches,and the lateral and longitudinal bearing of box girders are solved.The force problem is a new mode of assembly construction for bridge development.
