Shear wave (S-wave), whose oscillation direction is perpendicular to its propagation direction, is widely used in the laboratory and in the field to evaluate the small-strain stiffness of soils. This study investigated the correlation between S-wave oscillation directions and inner fabric of soil specimens by developing octagonal prism shape specimens and conducting S-wave propagation tests. The experimental results reveal that S-wave oscillation direction can capture the anisotropy of soil inner fabric.
