| 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,较真实地反映了工程的实际情况,对自由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。并对比了其与弹性地基模型上道面板的弯沉,说明地基粘性效应限制了板的冲击挠度的发展,对工程设计的改进具有一定意义。

| Abstract: | Mechanic calculation model of elastic pavement slab on viscoelastic foundation under impact load is established,which reflects the practical situation of engineering.The motion equation of slab under free boundary condition is solved using finite Fourier transform.The solution is compared with slab deflection on elastic foundation model,which indicates that viscous effect of foundation confines dynamic deflection of slab.It has certain significance to engineering design＇s improvement. |
