| 摘 要： | 分析了铁路桥梁横向刚度的内蕴，提出了适用于列车过桥的舒适度表达式，建议以水平挠跨比作为横向刚度的评价尺度。在此基础上，考虑加速度的概率分布，得出了确定允许挠跨比的理论方法，并通过算例予以验证。

| Abstract: | Contents of lateral stiffness of railway bridge are analysed, expressions of comfortable range, with horizontal f/L ratio as evaluation scale of lateral stiffness, for a train passing through a bridge are proposed, and furthermore, theoretic methods, considering accerleration probabilty distribution, for determining allowable f/L ratio are established and verified with calculation examples. |
