EFFECT OF SAMPLE DISTURBANCE ON STRESS-STRAIN BEHAVIOR OF COHESIVE SOILS

Different effects of sample disturbance were simulated in strain behavior when the sample is subjected to e.g. swelling, reconsolidation, shear strain or total stress changes. A new framework is suggested which applies the concept of "reference strain". It is based on results of laboratory and field measurement. The normalized behavior of a soil can be determined with high accuracy in the laboratory. By also measuring the shear strength and initial tangent modulus in the field it is possible to accurately describe insitu stress-strain behavior. /Author/
