摘　　要：在总结既有文献计算结论的基础上,综合分析实际测试结果的数据,应用桥梁、钢轨相互作用原理及计算模型,分析了铁路连续梁桥有碴轨道上铺设无缝线路情况下,钢轨伸缩附加力的作用机理及分布规律。According to existing calculation theories, actual experimentation data are analyzed synthetically. Based on the inter-action principle and calculating model of beam and rail, the distributing rule and effect mechanism of the expansion and contraction forces of welded rails are analyzed when continuously welded rail is laid on continuous railway beam bridge.
