| 摘 要： | 文章基于线弹性断裂力学的有限元法,对沥青路面开裂以后的温度应力及裂缝在温度作用下的扩展规律、裂缝尖端的应力强度因子及其与路面温度分布和路面材料特性等参数之间的关系进行了数值分析。结果表明,合理设计沥青面层的厚度和优选温缩性小的路面材料是提高沥青路面抗裂性能的重要方法。

| Abstract: | Based on the finite element method for liner elastic fracture mechanics,this article makes a numerical analysis on the relationship among temperature stresses after asphalt pavement cracking,extension law of crevices under the temperature,stress intensity factor of crack tip,pavement temperature distribution and pavement material characteristic.The result shows that rational designing on thickness of asphalt surface coat and selecting low temperature stressed pavement material are important methods to improve the cracking resistance of asphalt pavement. |
