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 appearance of early cracks in asphalt pavement reduces the service life of the road. In order to study the crack propagation behavior of asphalt pavement surface under use, based on the fracture mechanics theory, the change law of crack stress strength factor K11 under moving load was analyzed by using the finite element software ABAQUS, the pavement response under different crack cracking depths and different interlayer frictional contact conditions was studied, and the influence of pavement structural parameters such as surface thickness, surface layer and base modulus on crack propagation was discussed. It provides a theoretical reference for the rational design of semi-rigid base asphalt pavement and the maintenance and maintenance of asphalt pavement.
