| 摘 要： | 采用矩形轮胎接地形状,用ANSYS软件建立道路模型进行力学计算,分析超载对半刚性基层沥青路面的力学影响和路面基层、面层的断裂力学计算。结果表明,面层的剪应力、拉应力都随轴载的增加而增长;超载对沥青路面的早期断裂破坏影响严重。

| Abstract: | The mechanical effect of overload on asphalt pavement with semi-rigid base course was calculated in facture mechanics computation for both the base and the surface by using rectangular tire grounding pattern,with ANSYS software to build up pavement model for mechanical computation.The results have shown that the shear,the tensile stress on the surface increase with the increase of axle load,and they would result in serious effect of overload on the earlier damage of asphalt pavement. |
