摘要
推导出了半正弦荷载作用下基于修正Burgers模型的沥青混合料变形特性力学模型,并通过O rigin7.5软件进行了动三轴重复荷载试验数据的模型参数拟合,拟合模型参数的变化规律与理论分析一致,且拟合相关度高,初步表明了推导模型的准确、合理。
In this paper, a stress-strain model of asphalt mixture under haversine wave loads based on modified Burgers model was deducted, and with the software of Origin 7.5, the model parameters was fitted on the datas of dynamic triaxial test. From the perfect fitting dependency and consistencey of the variety rule for the fitting model parameters, it is indicated that the deducted model was accurate and reansonable.
