This paper is absorbed in the research of the nondestructive testing theory about airport rigid pavements , which is on semi - infinite viscoelastic foundation to moving load 这就需要在科学的评价体系下,有针对性的对道面进行检测、分析、评价和预测。
The pavement system is modeled as a plate extent on a viscoelastic foundation , and the triple fourier transform is used to analyze the dynamic strain response of rigid pavement subjected to moving vehicle loads 摘要把刚性路面建模为黏弹性地基上的板,用三次富立叶变换的分析方法分析了移动车载下刚性路面板底动态应变的响应。
In the present , the models used widely are two kinds : the continuous model . the continuous model is supported by " smearing out " the discrete support along the track . giving a continuous viscoelastic foundation and a continuous layer represent sleepers 目前所使用的计算模型主要分为两种:一种为连续型模型:将沿轨道方向的离散支撑连续化,将枕木模拟为刚体或为有均布质量和刚度的梁,使枕木成为粘弹性地基上的连续层。
