Abstract
Two different types of undisturbed cylindrical specimen (V-specimen: the axis is parallel to the direction of sedimentation, and H-specimen: the axis is perpendicular to the direction of sedimentation), were prepared from high quality undisturbed sand column obtained by in-situ freezing technique. A series of drained compression and extension tests (CD, test, CD, test) and cyclic undrained triaxial tests (liquefaction test) on these samples were performed in order to investigate the effect of the anisotropy on the drained and undrained shear behavior. Following were concluded. 1) The effect of anisotropy on both internal friction angle and liquefaction strength is negligible. 2) The difference in deformation characteristics between V and H-specimens for Holocene soil layer appeared in both CD and liquefaction tests implies that in-situ soil is easier to compress in horizontal direction than in vertical direction. 3) The effect of anisotropy on deformation characteristic of Pleistocene sand samples is not so remarkable as that of Holocene sand.
