| 摘 要： | 利用ANSYS对沥青路面温度场进行模拟，并与结构耦合，计算日周期气温下路面结构的温度应力。在有限元分析过程中，考虑了沥青混和料劲度模量、温缩系数是温度场函数的关系。分析结果表明，沥青路面温度应力分析时应考虑温度场在时间和空间上的变化以及温度场对材料热工参数的影响。

| Abstract: | In order to simulate the temperature field of asphalt pavement, a finite element model is built by using ANSYS. Coupling the temperature field results with asphalt pavement structure, thermal-stress can be analyzed under the daily air temperature condition. During the simulation analysis the influence of temperature-dependent material properties, such as asphalt mixture stiffness and coeifcient of thermal expansion, has been taken into account to make the simulation in line with the real situation as much as possible. |
