NORMALIZED STRESS-STAIN BEHAVIOR OF TIANJIN SOFT DREDGER SOIL

The stress-strain relations of Tianjin soft dredger soil is strain hardening,which can be fitted by kondner hyperbolic curve.Based on this,The paper used four kinds of normalization factors to study stress-strain characteristics of CU test of Tianjin soft dredger soil,and also established the normalized equation.The research indicated that using thses four kinds of normalization factors to carry on normalization,the normalized degree is highest when used (1-3)ulti as normalization factor,when used 3 as normalization factor,the normalized degree is lowest,while used (3)n as normalization factor,n takes 0.55～0.65 appropriately.
