| 摘 要： | 沥青路面早期裂缝的出现,降低了道路的使用年限.为了研究使用状态下沥青路面表面裂缝的扩展行为,基于断裂力学理论,应用有限元软件ABAQUS,分析了移动荷载下裂缝应力强度因子K11的变化规律,研究了不同裂缝开裂深度和不同的层间摩擦接触状况下的路面响应,并探讨了面层厚度、面层和基层模量等路面结构参数对裂缝扩展的影响.为半刚性基层沥青路面的合理化设计和沥青路面的维修养护提供一定的理论参考.

| Abstract: | The usage limit of road decreases with the appearance of asphalt pavement early crack.In order to study the propagation behavior of asphalt pavement surface crack in use,the change law of the stress intensity factor K11 of surface crack was analyzed under moving load with the commerce FEM software ABAQUS based on fracture mechanics theory.The response of asphalt pavement with surface crack was studied under the condition of different crack depth and different frictional contact status between layers.The eff... |
