This paper demonstrated an experimental study on the properties and the effects of anisotropy of sand by using a hollow cylindrical shear apparatus. After discussing the effect of initial anisotropy, we experimentally demonstrated the effect of induced anisotropy on undrained shear behavior. The test data of the specimens with prior shear history showed that induced anisotropy derived a pseudo-density change as well as initial anisotropy did. Similar behavior to dense specimens was exhibited when the direction of the second loading was the same as that of the first loading. These experiments captured a developing process of anisotropy. The test data displayed in this study would update our knowledge regarding the anisotropy of sands and lead to the development of a sophisticated constitutive model for soils.
