| 摘 要： | 建立轮胎接地形状分别为圆形和矩形两种沥青路面结构有限元模型,并对建模计算结果误差进行对比分析,并与HPDS设计程序计算结果进行比较。结果表明,沥青路面轮载接地形状对路表的影响大于面层层底和基层层底,对剪应力的影响比较大,但这些结果对HPDS设计的结果影响不大,基本接近,矩形形式的荷载结果更接近HPDS程序设计结果。说明轮胎接地形式在有限元分析中采用矩形形式是可行的。

| Abstract: | The established tire contact shape is circular and rectangular finite element models for two finite element modeling of asphalt structure,respectively.The calculation errors of modeling results were compared with those of HPDS design programme.The results have shown that the effect of tire contact shape of wheel load on road surface is larger than on the bottom of the wearing course and the subbase,with relatively larger effect on shear stress and little on HPDS design results,just as the basic approach.The... |
