| 摘 要： | 根据薄板假定,采用文克勒地基模型,本文推导了文克勒地基上无限大板的纵向振动微分方程。然后用Hankel-Laplace变换获得了任意轴对称荷载作用下的挠度解。为了对路面落锤式弯沉仪测定数据进行理论分析,基于落锤式弯沉仪的加载过程为半波正弦曲线的假定,获得了该荷载作用下文克勒地基上无限大板的挠度解。

| Abstract: | In this paper, the longitudinal dynamic equation of plate on Winkler foundation is derived with thin plate assumption and Winkler foundation model. The displacement formula of plate under any symmetric load is derived, in which the Hankel-Laplace transformation is used. In order to analyze the test results obtained by using Failing Weight Deflectometer(FWD), the semi-sine load of FWD is assumed in this paper and the theoretical solution under this load is got. It is important to the analysis of dynamic response of pavement. |
