In this study, evaluation of samples' reflection of in-situ condition was performed for those by 225 mm KICT large sampler and NX size piston sampler. Disturbance analysis was conducted for the clay sampled by two kinds of sampler throughout consolidation tests, uniaxial tests and triaxial test, under the same condition. From the analysis it can be seen that not only the initial void ratio and preconsolidation pressure from KICT large sampler but strength parameters from both uniaxial and triaxial compression tests are also about 10% higher than those of NX size piston sampler's.
