摘　　要：经济高速的发展对道路等级和城市道路网系统的建设提出了更高的要求,此时涌现出大量的斜桥,而正桥是斜交角为0°的特例。影响斜桥横向分布系数的因素很多,本文利用Midas civil建立有限元模型,主要分析斜交角对横向分布的影响,研究发现,横向分布系数会随着斜交角度的增大而减小,并通过实桥荷载试验进行验证。With the rapid development of economy and the improvement of road grade and the con- struction of urban road network, inclined bridge emerged at this time and right bridge is a special case of the skew angle of 0°. There are many influence factors in oblique bridge transverse distribution coefficient. In this paper, Midas civil finite element model is established, the influence of skew angle on the transverse distribution is mainly analyzed. The study found that the horizontal distribution coefficient decreases with the increase of skew angle, and it is verified by actual bridge load test.
