摘要
采用有限单元法,对带接缝的旧水泥混凝土路面沥青混凝土罩面层在车辆移动荷载作用下的力学响应情况进行了三维瞬态数值分析.通过接触方法进行分析,能够更为准确地分析移动车载对路面的作用情况,分析的结果能够定量地解释荷载型反射裂缝.
In the paper, the mechanics response of an asphalt overlay on the cement concrete pavement with joints under moving loads is quantitatively analyzed by finite element method. The interaction between tires and road is simulated through contact analysis. The analysis results can be used to explain how the moving loads cause the reflection cracking.
