摘　　要：在总结已有文献计算结论的基础上,综合分析实际测试数据,建立桥上无缝线路梁轨相互作用的力学模型,采用有限元方法和C++语言编程,研究、计算特殊设计的混凝土简支梁桥上无缝线路钢轨断轨力的分布及其对桥梁墩台的传递规律。Summarizing the conclusions of computation in available literatures and analyzing synthetically actual experimental data, the paper established an interaction model of beam and rail, and by adopting FEM and a program compiled by C ＋＋ language, this paper studied and calculated the rupture forces in the continuously welded rails （CWR） on a specially-designed simply-supported reinforced concrete bridge, and the distribution of rupture forces in rails as well as the law of their transmission to bridge piers and abutments.
