| 摘 要： | 建立了冲击荷载作用下粘弹性地基上弹性道面板力学计算模型,比较真实的反映了工程实际情况,对简支边界条件下板的运动方程,采用有限傅立叶变换等手段进行了求解。并对比了其与自由边界条件下道面板的弯沉,说明以简支边界作为场道工程中刚性道面板的边界条件进行求解,会增加混凝土材料的用量。

| Abstract: | A limited Fourier transform is employed to investigate the dynamic response of elastic plate which has simply-supported boundary conditions on a viscoelastic foundation under impact loading.By comparing the result that free and simply supported edge pavements on the viscosity of the foundation,this paper gives a conclusion that the simply edge will be to increase the materials. |
