摘　　要：采用广义梁格法进行斜桥活载效应分析,考虑横梁对横向分布的影响,描述了该方法对不同形式斜桥计算时的参数取值,采用Fortran语言编制了相应的程序,通过计算得出拓宽后的桥梁活载内力并讨论了不同形式斜桥的活载内力变化规律。Cross beam effct to lateral distribution is considered and live load effect is analysized using generalized grillage simulation, How to adopt parameters is described when using this method to calculate different kinds of skew bridges, The interrelated programme is completed using Fortune 90. The forces of the widened bridge are calculated and the changing＇ rules about different kinds of skew bridges are discussed. The conclusions have some reference value to skew bridge design.
