| 摘 要： | 使用本构模型来模拟路面面层材料的本构关系,同时将行车荷载的作用形式视为半正弦波谱形式,通过大型通用有限元的二次开发功能,开发出在任意荷位进行循环加载的有限元子程序,分析了加载速率和荷载间歇时间对疲劳裂纹扩展的影响。

| Abstract: | The generalized Maxwell model is used to simulate surface material of asphalt pavements.Taking the form of traffic load as half sine wave,using the second development function of large general finite element program,finite element subroutine of cyclic loading in arbitrary position are built.The influence of loading rate and intermittent time on crack propagation is analyzed. |
