摘　　要：通过Abaqus软件建立三维节段模型,分析了空间受力特性表明该桥的横向受力满足规范要求,分析了箱间加肋桥面板的受力分布形态和极限承载力,表明箱间加肋桥面板受力不同于箱内桥面板,箱间加肋桥面板为双向受力构件,有着足够高的安全储备。Three-dimensional segment model is established by Abaqus software.The spatial stress analysis shows that the transverse stress of the bridge meets the requirements of the specification.The analysis of the stress distribution and ultimate bearing capacity of the box stiffened bridge deck shows that the stress of the box stiffened bridge deck is different from that of the box deck.The box stiffened bridge deck is a two-way load-bearing member,with enough high safety reserves.
