摘　　要：建立了桥上无缝线路梁轨相互作用的力学模型,采用有限元方法计算研究了特殊设计的混凝土简支梁桥无缝线路钢轨附加挠曲力的分布,得出的结论可以指导桥上无缝线路的设计,可供相关技术人员参考。Basing on interrelated action principium of beam and rail, we build a mechanics model and use finite dement method to calculate and analyze the principle of discrete force of welded railway on special designed simple supported bridges. The result can give some advice to the design of continuously wdded rails on bridges, which to ofter a reference for rdevant technical staft.
