The Experimental Method Has Studied The Deformation Properties And Parameters Of The Frozen Viscous Soil

In this paper,the artificial frozen free clay as the object of study,respectively,under different conditions of frozen soil uniaxial compression characteristics and strength,uniaxial creep law and its influencing factors.The results show that the curve shows the strain hardening and the freezing temperature is constant.When the freezing temperature is constant,In the range of water content,the uniaxial compressive strength of artificial frozen soil increases with the increase of water content.When the water content is constant,the uniaxial compressive strength of artificial frozen soil decreases with the freezing temperature And increase.According to the uniaxial compression creep test,the axial strain under multi-sample single-stage loading test is larger than the axial strain under single sample loading test,and the constitutive equation is used to describe the creep deformation (?),There are linear relationships between the creep parameters A,B,C and K under different test methods,and the accuracy of the constitutive equation is verified by the creep parameter inversion.According to the stress-strain isochronal curve,the third yield strength and the elastic modulus of the frozen soil are obtained with the increase of time.The relationship between the elastic modulus and the time can be described by the mechanical model (?)。The third yield strength and time relationship can be described in terms of (?) shape,and the correlation between strength and elastic modulus in time is proved.
