    Abstract

    The effect of tube wall friction on the microstructure of Ariake clay samples obtained from a small diameter sampler (45-mm sampler) and their strength and consolidation properties are examined from use of a color laser three-dimensional profile microscope plus unconfined compression, triaxial compression, and standard oedometer tests. The microstructure within 2 mm of the tube wall was disturbed due to wall friction. However, the disturbance in the rest of the sample had other causes and the samples were mechanically homogeneous. The unconfined compressive strength and preconsolidation pressure values obtained from the 45-mm sampler were 20 % to 40 % greater than those of the 75-mm sampler and their sample quality therefore higher.
