Abstract

Abstract: Based on the linear elastic fracture mechanics and the finite element analysis method，this thesis analyzes the crack growth on the understratum with cracks of the surface of the asphalt pavement under coupling effect of vehicle load and hydrodynamic pressure． The result shows that the hydrodynamic pressure significantly changes the crack growth regularity of the understratum of the asphalt surface under symmetrical load and partial load． As the hydrodynamic pressure increases， the crack-tip shows compound forms of stretching growth and shearing growth，which accelerates the damage of the asphalt pavement．

Key words: asphalt pavement, hydrodynamic pressure, vehicle load, coupling effect, crack growth, finite element analysis

摘要： 基于线弹性断裂力学原理和有限元分析方法，对汽车荷载与动水压力耦合作用的面层层底含裂纹的沥青路面进行裂纹扩展规律研究与分析。结果表明: 动水压力的作用明显改变了对称荷载与偏荷载作用下沥青面层层底的裂纹扩展规律，并随着动水压力增大，裂纹尖端呈现张拉型扩展与剪切型扩展共同作用的复合形式，从而加速了沥青路面的破坏。
