摘　　要：以单跨斜梁桥为例,从弯扭耦合、支座反力分布、梁体弯矩等方面介绍了斜梁桥的力学特点,并同正交梁桥比较,分析了其力学特征产生的原因,为同类型斜梁桥力学特性分析积累了经验,从而完善斜梁桥的设计。Taking single span skew girder bridge as example, the mechanics feature of skew girder bridge was introduced from bend coupling, support reaction distribution and beam body moment, which was compared with orthogonal beam bridge, and the reason of causing mechanics feature was analyzed, which accumulate experience for mechanics feature analysis of similar type skew girder bridge, so as to perfect the design of skew girder bridge.
