The paper presents analysis of stabilized soft clay stress-strain behaviour based on drained triaxial test results performed on stabilized and reconstituted soft clay. Main parameters concerning sample preparation and affecting efficiency of stabilization are addressed. Throughout the paper stabilized clay behaviour is compared to that of normally and overconsolidated soil. It has been done so in order to determine characteristic phenomena of stabilized clay behaviour with the main emphasis on effects of structure on strain hardening, strain softening, strength parameters and volume change behaviour.
