摘 要: 根据某灰色软黏土的室内流变试验的试验结果,在流变理论的基础上,对软黏土应力应变等时曲线进行分离和分解,分析了土体的流变特性;建立了土体流变的本构模型,并应用最小二乘法和回归分析等数值分析的方法确定模型参数,得出了一些有参考价值的结论。 On the basis of the results obtained from the gray soft-soil laboratory rheologic test in henan province, the rheologic curves are divided or decomposed according to theological theory. The rheoligic characters of soil are analysed.The rheology constitutive model of soft soil is constructed, By the least square techniques and binary linear regression analysis etc,the parameters can be obtained in the rheoligic constitutive model. We can draw some beneficial conclusions.
