摘　　要：文中以主跨185m的波形钢腹板连续刚构桥为工程背景,研究横隔板对桥梁受力的影响。结果表明,采用合适的横隔板的布置方式,可以增大箱梁抗扭刚度,减小翘曲应力和底板横向正应力。In this paper,the influence of diaphragm on the stress of the bridge is studied based on the engineering background of 185 mcomposite girder bridge with corrugated steel webs,The results show that the appropriate arrangement of diaphragm can increase the torsional stiffness of box girder,reduce the warping stress and transverse normal stress of bottom plate.

关 键 词：波形钢腹板 横隔板 扭转刚度 翘曲应力 横向应力
