| 摘 要： | 为了获得高模量沥青混凝土的粘弹性本构关系,分析了ABAQUS自带的时间硬化蠕变模型Bailey-Norton,对其蠕变规律进行积分处理,建立了新的实用模型；结合单轴压缩蠕变试验中采集到的蠕变数据,利用ISTOPT拟合软件进行回归计算,得到了高模量沥青混凝土在不同温度下的蠕变参数.

| Abstract: | In order to obtain the viscoelastic constitutive relation of high modulus asphalt concrete,the Bailey-Norton creep model of ABAQUS was analyzed,and the integral processing was conducted on the creep laws, based on which a new practical model was established.Combined with the data collected from the creep tests of uniaxial compression,the regression calculation was conducted with ISTOPT,and the creep parameters at diverse temperatures were obtained for high modulus asphalt concrete. |
