Abstract

Abstract

On the basis of a series of indoor tests for unsaturated Nanning expansive soils through creep testing apparatus controlled by shearing force,nonliner rheological characteristics of the expansive soils were researched.The results show that the soil performs for attenuation when shear stress is less than or equal to 25.5 kPa,but the soil has obvious non linear rheological behavior when shear stress is higher than 25.5 kPa.Through the experiment creep curve can be described by Burgers model,the constitutive equation and the creep equation of the expansive soils also be obtained.
