摘要
建立沥青路面有限元模型,按照我国沥青路面设计规范对所建模型施加1次标准荷载进行静力分析,然后施加200万次的循环标准荷载,进行疲劳破坏分析。模拟结果表明,在仅考虑载荷作用时,沥青路面疲劳破坏首先发生在轮迹中心处,然后向两侧扩展。
Finite element model is built and the standard axle loading is applied for one time and 200 million times according to specification for the design of highway asphalt pavement.Then fatigue analysis is carried out.Simulation results show that asphalt pavement fatigue failure first occurs in the center of wheel traces and then develop to the two sides if the loading effect alone is under consideration.
