Abstract

Fabric anisotropy of a granular soil may strongly influence its engineering properties and behavior. This paper presents the results of a new experimental study designed to measure the anisotropic shear moduli by simulating fabric anisotropy. Piezoelectric transducers were used to obtain the elastic shear modulus in vertical, horizontal, and 45° inclined planes (G_vh, G_hh, G_ah) of samples prepared by 0°, 45°, and 90° deposition angles. The measurements show a significant difference of G in these planes in soil samples because of the fabric anisotropy.
