摘要:
为了研究冻融循环作用下水泥沥青复合胶结料的粘弹性力学行为,本文进行了CACB材料的冻融及蠕变试验。建立了四元件五参数的粘弹性力学模型,通过对蠕变试验结果的拟合分析,建立了CACB材料的本构方程。基于本构方程参数随冻融次数的变化,分析了冻融对CACB材料粘弹性力学行为的影响规律。研究表明:冻融作用降低了CACB材料抵抗瞬时弹性变形及剪切流动变形的能力,CACB材料的弹性性能受冻融作用的影响更为显著。粘弹性本构方程材料参数的变化可以反映CACB材料宏观力学性能的冻融损伤过程。冻融循环作用没有改变CACB材料的粘弹性属性,随着沥青含量的增加及温度的提高,CACB材料趋向于粘性材料的性质,抵抗载荷的能力降低、变形能力增强。
