摘要
本文首先分析了材料线粘弹性的各种模型．其次对水泥砼路面材料粘弹性试验进行了研究．最后运用最小二乘法原理及回归迭代方法，编制了根据材料粘弹性试验曲线推算各模型参数的计算机程序ＶＤＴ，并使用该程序对试验资料进行了回归分析，得到了较好的成果．这为考虑材料粘弹性水泥砼路面的温度应力计算提供了参数，具有一定的实用价值．
First,various kinds of material visco-elastic models are analysed.Visco-elastic test is studied on cementconcrete pavement Second,using minimum vsriance principle and regression analysis method computer program VDT is drawn up.Finally,visco-elastic parameters are obtained according to test curves.It has practical value for calculating curling stresses on cement pavement.
