| 摘 要： | 路面裂缝尖端应力强度因子和J积分是判断裂缝开裂扩展的重要指标,应用商业通用有限元软件ABAQUS,建立了8节点等参单元的有限元模型,采用奇异单元及断裂力学理论,对江苏省典型的半刚性基层沥青路面结构裂缝问题进行了荷载和温度应力数值分析,结果能反映路面破坏的现象和规律,为分析沥青路面开裂提供依据。

| Abstract: | The stress intensity factor and J integral at the pavement crack tip is an important index to judge the crack to grow or not. In this paper a finite element analysis model of 8-node isoparametric elements was established by the commercial FEM software ABAQUS and the crack of asphalt pavement which caused by temperature and load was analysed with the singularity isoparametric elements and fracture mechanics theory for the typical asphalt pavement structure of Jiangsu province.The road destroy phenomenon and law can be truly imaged from the results and be provided to the crack. |
