| 摘 要： | 通过选用具有代表性的全厚式沥青路面和半刚性基层沥青路面，利用ANSYS有限元计算软件，建立路面结构三维模型对路面在车辆荷载作用下的力学响应进行分析．可知全厚式沥青路面在抗疲劳损坏和永久变形方面都较半刚性基层沥青路面略胜一筹，且寿命更长．因而具有广阔的应用前景。

| Abstract: | Based on the pavement structure three-dimensional model through finite-element calculation software（ANSYS）, the representative full-depth asphalt pavement and asphalt pavement with semi-rigid base are analyzed in the aspect of mechanical response under the action of vehicle load. It can be known that the full-depth asphalt pavement is better than the asphalt pavement with semi-rigid in anti-fatigue damage and permanent deformation, what＇s more, the lifespan is longer. It has brighter application prospect. |
