| 摘 要： | 利用级数展开法和Laplace--Fourier变换推导了文克尔地基上无限长板在半波正弦瞬态荷载作用下位移和应力的解析解。计算和分析了板的位移响应情况，并和弹性地基静荷载情况的位移进行了比较，讨论了荷载作用时间、地基参数及板参数等对位移响应的影响。对路面设计、品质评价及破坏机理分析有重要意义。

| Abstract: | Based on the thin plate and Winkler foundation model, transient dynamic response of a viscoelastic foundation supported infinite strip due to the semi-sine load of FWD has been studied. Analytical solution for displacement and stresses were obtained, with the help of triangular series method in combination with the Laplace-Fourier transform method. Numerical results were given and compared with the response of the plate under static and transient load on elastic foundation. Finally, the influence of transient load period, physical parameter of foundation and plate were dis- cussed. The theory developed herein may be used as a preliminary reference in pavement engineering design. |
