摘要
构建有限元分析模型,分析路面内部温度场变化规律,以此为基础分析不同温度以及行车荷载对沥青路面车辙发展情况的影响。研究表明:高温条件下车辙发展速度远大于低温条件下的发展速度;车辙深度与荷载大小呈线性相关;对于同样的荷载增长幅度,较低温度下车辙的增长幅度更大,但高温条件下车辙深度增长绝对值则更大。
This paper analyzes the change rules of internal pavement temperature field by Finite Element Analysis Model, on the basis of which the author analyzes the influence of different temperatures and traffic load on asphalt pavement rutting. The study shows that rutting develops more quickly in high temperature than in low temperature, and that in the condition of same load frequency, the rut depth is linearly correlated with load size. The same load growth leads to greater rut growth in low temperature, but the absolute value of rut depth growth is greater in high temperature.
