摘　　要：对工程界有争议的斜梁桥横向刚度问题进行了较深入的研究。通过内力影响面，比较了阶梯中横梁与正交横梁之间的差异，分析了弯扭剪之间的耦合作用，获得了有关合理横向刚度的结论，据此提出了相关工程设计建议。This paper deeply studies the problem of transverse stiffness of skew girder bridge which has been argued for a long time. After analysis of coupling among the bending, shearing and torsion in the infulence surface of internal forces, the difference between the orthogonal and stepped diaphragms is compared, the rational transverse stiffness is obtained, and the design method is proposed.

关 键 词：斜梁桥 内力影响面 中横梁 端横梁 横向刚度
