THE DYNAMIC RESPONSE OF ANISOTROPIC CLAY

The process of sedimentation followed by one dimensional consolidation results in natural clays having cross anisotropic mechanical properties with the axis of symmetry along the direction of consolidation. The results of the experimental investigation described in this paper demonstrate the importance of the clay fabric and the influence it has on the dynamic behavior. At high frequency loadings it is shown that substantial differences exist among the moduli obtained from vertical and horizontal specimens. At low frequency cyclic loading it is shown that the responses of the isotropic and anisotropic materials are totally different. An anisotropic clay does not turn into anisotropic one even under the most severe cyclic strains. Axial compression and extension tests cannot be substitued for simple shear tests in evaluating the dynamic properties of an anisotropic clay. /Author/
