| 摘 要： | 本文以包括钢轨、轨枕、道床在内的轨道作为双层结构模型。分析了轨道在移动简谐荷载作用下的动力响应，并与定点荷载作用的结果作了比较，指出了二者的差异，并建议在分析高速铁路轨道动力响应时考虑到车速度的影响，以及转向架邻轮和阻尼的作用。

| Abstract: | The study of dynamic response of railway track, treated as a two layer structure model including rail sleeper and ballast under moving oscillating load, is given. It is then compared with that under unmoving oscillating load, with their differences point out. The results show that when the effects of train speed, damper and adjoining wheel-load should be considered. |
