摘　　要：针对宽跨比较大的异型连续箱梁的横隔梁设置问题,运用梁格法原理对雾凇异型连续箱梁建模,拟定了三种横隔梁设置方案。在不同荷载工况作用下,运用有限元分析软件MIDASCivil对三种不同方案的内力加以分析。结果表明:对于该结构的连续箱梁,除端部和中墩墩顶处设置横隔梁外,各跨跨中以不设横隔梁为佳。文中对异型连续箱梁的设计内力取值,可为其他类似结构设计提供参考。Aimed at addressing the layout of horizontal beam of heterotypic continuous box girder with large span, this paper features a model designed for Wusong heterotypic continuous box girder with basic theory of beam grid, and offers three different programmers of layout of horizontal beam. The paper, based on the different load conditions , privodes an analysis of internal forces of three different programmers with the MIDAS Civil of finite element analysis software. The Research result shows that, except that the tip and middle pier carries horizontal beam, it is advisable that the kind of continuous box girder be subjected to no horizontal beam in the middle of each span. The design value of internal force can offer reference for other similar structural design.
