| 摘 要： | 建立了有碴轨道结构路桥过渡段的有限元计算模型，利用ANSYS有限元分析软件，计算了在静力作用下，不设置过渡段和过渡段长度分别为10m，20m和30m时，钢轨的位移和转角，提出了确定过渡段长度的部分理论依据。

| Abstract: | A model of the track on roadbed-bridge transition section is established. The distribution of displacement and rotation angle are cal-culated for static leads when not setting transition section or setting different length which is 10 m, 20 m, 30 m of mmsition section with the finite dement analysis software ANSYS. Some theoretical bases for determining the reasonable length of the roadbed-bridge transition section have been discovered. |
