STUDY ON SHEAR WAVE VELOCITY DURING CONSOLIDATION AND LIQUEFACTION CHARACTERISTICS OF ARTIFICIALLY CEMENTED SAND

Abstract

 Pleistocene sandy soil are more stabilized in terms of physical and chemical properties than Holocene sandy soil. It is difficult to quantify the effect of the stabilization on liquefaction characteristics, and the conventional liquefaction assessment method has been done within the same framework as conventional sandy soil. In this study, shear wave velocity, which was introduced to quantify soil fabric in previous studies, is applied to the artificially cemented test specimen to investigate the effect on the soil structure. In addition, undrained cyclic loading tests were carried out to discuss the stress path, stress-strain relationship and normalized loss energy.
