| 摘 要： | 本文首先研究了粘弹性地基上四边自由矩形板在运动载荷作用下的动态响应问题,得到了问题的近似解答。然后从该解答出发讨论了机场道面的动态响应问题,并以××机场道面板为计算模型,将理论计算结果和实验结果进行比较,二者符合较好。最后计算了道面的固有频率、临界速度,讨论了主要物理参数对道面动挠度的影响规律。

| Abstract: | This paper discusses dynamic response of rectangular plates with free edges on viscoelastic foundation under moving loads and gives an approximate solution. The solution is used to solve the problem of dynamic response of airport pavement and an illustrative example is presented. The numerical results show good agreement with experiments. Finally, the curves and tables affected by different physical constants are given. |
