摘　　要：斜梁桥的力学特点与正交梁桥相比有很大区别。介绍斜梁桥的计算方法,通过对连续斜梁桥的空间有限元分析,讨论斜度、横向联系刚度及支承刚度对斜梁桥受力性能的影响,得出若干结论,并据此提出相关工程设计建议。The mechanical properties of a skew girder bridge differ a great deal from those of an orthogonal girder bridge. In this paper, the calculation methods for the skew girder bridge are introduced. Through analysis of a continuous skew girder bridge by means of the spatial three-dimensional finite element, the influences of the skew angles, transverse bracing stiffness and supporting stiffness on the mechanical behavior of the bridge are discussed, several conclusions in connection with the analysis of the bridge have been obtained and according to the analysis, the relevant proposals for design of skew girder bridges are made.
