The authors derived the elasto-plastic incremental stress-strain relationship of the cohesive soils based on the assumption that the cohesive soils are the strain-hardening materials not only for shear but also for compression. And we incorporated the effect of stress histories in the relationship, and not time-dependancy. In this paper, firstly the authors check up on the assumptions which were used to derive the relationship from the results of the repeated isotropic consolidation and mean principal stress constant tests on the Ariake Clay, and decide the soil parameters from these test results. Secondly we confirm the relationship by the comparision of the calculated and observed stress-strain behaviours on the Ariake Clay experienced some stress histories, and compare the relationship with the theory of Roscoe and Burland.
