Abstract
This study investigates the effect of non-plastic fines on the anisotropic smalls strain stiffness of a calcareous sand by conducting multidirectional bender element tests. G(HH), G(HV) and G(VH) are evaluated on both horizontal and vertical planes and the stiffness anisotropy, considering the effect of fine content, is studied. The models for predicting small strain shear modulus G(0) of the calcareous sands are modified. Test results show that G(0) decreases with the increase of the fine content until a threshold fine content is reached. The stiffness anisotropy drops with the increases of the fine content. The modified Hardin equation provides a better prediction than the modified Wichtmann equation and the Payan equation.
