摘　　要：波形钢腹板箱梁是一种新型的钢-砼组合结构,结合其结构特点并以某拟建工程为依托,通过有限元软件对其在不同腹板倾角下的受力状况进行分析,比较各种工况下梁体的跨中挠度、底板砼应力及钢腹板剪应力等受力情况而得出结论,为实桥的设计和施工提供理论依据.The box girder with corrugated steel webs is a new type of composite steel - concrete structure. Combine to it＇ s structure feature, analysis the mechanical behaviors of the different inclination of webs according to the finite dement program. Compared with the finite element model＇s deflection.flexural stress and shear stress in different inclination of webs, it can make some conclusions that can provide theoretical foundation for bridge design and construction in future.
