| 摘 要： | 斜交异形桥梁具有特殊的结构性能。本文从能量原理出发，导出了一般简支斜交桥的总体内力和位移的表达式，在此基础上，分析了斜交角、弯扭刚度比、荷载作用位置等因素对斜交桥性能的影响，得出了一些具有普遍意义的结论。

| Abstract: | Skew arbitrary bridges have special structural behaviour.In this paper,the equations of to-tal internal forces and displacements of simply supported skew bridges are derived by means ofthe energy principle. The effects of skew angle,stiffness ratios of bend and torsion,locations ofloads on the behaviour of skew bridges are studied in detail.Some general conclusions are ob-tained. |
