| 摘 要： | 沥青路面力学分析时,车辆荷载基本是被处理成通过轮胎与路面的接触面传递的,而且接触面假设为较为规则的几何形状以方便计算分析。通过对圆形、正方形、长方形、椭圆形及矩形+两半圆形接触面的荷载处理方式进行三维有限元计算,结果显示:矩形+两半圆形的接触面对竖向位移、面层剪应力及上面层层底拉应力响应是最敏感的;对下面层层底拉应力的响应最敏感的是长方形接触面;圆形接触面对路面的变形和应力力学响应是最不敏感的,其次是正方形接触面。

| Abstract: | When analyzing mechanical property of asphalt pavement,vehicle loading is considered to be transferred through tyres to the pavement and the interface between the tyres and pavement is assumed to be in regular geometric shapes to facilitate calculation.Three-dimentional finite element method was adopted to evaluate the response of asphalt pavement subjected to vehicle loading with varied tyre-pavement interfaces,including round,square,rectangular,elliptical,rectangular plus two semi-rounds,respectively.The ... |
