Stress-strain relations for soils depend heavily on consolidation stress.The relativity appears as normalization character of clays silty.Clay is wildly distributed over Handan area,and often used as the bearing stratum of buildings.This paper analyses the normalization condition of stress-strain relation for clays of Handan in consolidated undrained triaxial test.The results show that if stress-stain relation of soils is considered as the Kondner hyperbolic function,the normalization character is bad whenσ₃,σ_m and(σ₁-σ₃)_ult serve as parameters,and good when(σ₃)ⁿ and(σ_m)ⁿ are adopted;the best normalized curve is chosen then.
