摘　　要：本桥桥面板由各预制横梁的顶板及横梁间的纵向现浇板构成整体,并且采用双吊杆型式,因此桥面板的受载行为较为复杂。针对本桥特殊的桥面板型式,考虑拱肋、吊杆及桥面板的耦合作用,采用通用结构分析程序SAP5仿真计算出桥面板在各个阶段的受栽行为,为现场施工提供了有力的理论支持,也为类似桥面板的受载规律提供了一定的参考。Bridge slab of this bridge is composed of top plates of precast cross beams and longitudinal cast - in -place plates between cross beams, and the double suspender structure has been used, so the load of the bridge slab is complicated. Aiming at the special bridge slab style of this bridge and considering the coupling of arch ribs, suspenders and bridge slabs, the general structural analysis program SAPS has been used for an emulational calculation of the load of bridge slabs in each stage. It provides a powerful theoretical support for the construction in work - site and is also a reference for loading laws of the similar bridge slabs.
