Summary: | To examine the effect of the fabric anisotropy of sand and clay on the quasi-elastic modulus, the shear wave velocity in three different directions was measured by the bender element method on specimens with different fabric anisotropy. In addition, the Young's modulus was measured by cyclic triaxial test on small strain and monotonic loading test. Test results showed that; 1) the initial shear modulus obtained from the shear wave for propagating and vibrating parallel to the bedding plane is higher than the other two kinds of moduli, 2) the Young's modulus in the horizontal direction, Eh, is higher than that in the vertical direction, Ev, 3)the anisotropy of elastic modulus in NSF clay is more considerable than that in Toyoura sand in this study. |
