Abstract: First, various kinds of material visco-elastic mcxlels are analysed. Visco-elastic test is studied on cement concrete pavement. Second, using minimum variance 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.

Key words: cement concrete, pavement, visco-elastic, parameter

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.
