摘　　要：为了得到土的强度和变形之间的有机统一关系,反映区域性土的本构关系实验参数,本文根据归一化幂因子理论,从围压和平均固结压力两个方面论述了土的归一化理论,通过对邯郸粉质粘土的固结不排水三轴试验,得到了土的应力应变关系曲线,在此基础上用两种归一化方法分析了邯郸粉质粘土的性状,得到了归一化参数,为邯郸粉质粘土的本构关系研究提出了基本参数,可用于岩土工程理论与应用分析。In order to get the organic unity between the strength and deformation of soil and reflect the constitutive relation of regional soil by using experimental parameters,in this paper,based on theory of normalized power factor,the theory of normalization is discussed from two aspects of the confining pressure and the average consolidation pressure.By using consolidated undrained triaxial test about silty clay in Handan,the stress-strain curve can be got,at the same time,the normalization parameters,which will be used for the study of the constitutive relation about the silty clay in Handan,can be got by analyzing the property of the silty clay with two kinds of normalization methods.The parameters also can be referential for the application and analysis in Geotechnical Engineering.
