초록
In this study we have remolded marine clay sample collected along the vertical and horizontal directions and investigated the characteristics of the consolidation constant by Standard Consolidation Test (SCT) and Constant Rate of Strain (CRSC) methods. Also, we have studied the consolidation characteristics and application for weathered granite soil using SCT and CRSC methods for undisturbed and disturbed samples. As a result, values of pre-consolidation stress, compress index, excessive pore pressure and pore water pressure ratio of the marine clay were different due to different test methods(CRS and CRSC) and sampling directions (vertical and horizontal directions). Disturbed and undisturbed samples of the weathered granite soil have showed similar change aspect like marine caly during over-consolidated and normally consolidated stages.
Abstract
In this study we have remolded marine clay sample collected along the vertical and horizontal directions and investigated the characteristics of the consolidation constant by Standard Consolidation Test (SCT) and Constant Rate of Strain (CRSC) methods.

As a result, values of pre-consolidation stress, compress index, excessive pore pressure and pore water pressure ratio of the marine clay were different due to different test methods(CRS and CRSC) and sampling directions (vertical and horizontal directions). Disturbed and undisturbed samples of the weathered granite soil have showed similar change aspect like marine caly during over-consolidated and normally consolidated stages.
