摘要
为了改善公路沥青路面建设水平,总结了沥青路面裂缝分类方法,以某国道项目为研究对象,分析了横向裂缝、纵向裂缝、块裂等裂缝的破坏机理。同时,利用有限元软件建立该公路沥青路面的计算模型,并基于断裂力学理论,计算了不同工况下的应力强度因子和断裂韧度,判断裂缝发展趋势。
In order to improve the construction level of asphalt pavement on highways,the hazards and classification methods of asphalt pavement cracks were summarized.Taking a national highway project as the research object,the failure mechanisms of cracks such as transverse cracks,longitudinal cracks,block cracks,and cracking were analyzed.At the same time,the Finite element software was used to establish a calculation model for the asphalt pavement of the highway,and based on the theory of fracture mechanics,the stress intensity factors and fracture toughness under different working conditions were calculated to determine the development trend of cracks.
