Stress-strain strength characteristics of a marine soil with different clay contents

It is commonly believed that the clay content has a major influence on the behavior of a soil, among other factors. This technical note presents main results of a series of consolidated undrained (CU) triaxial tests on re-consolidated soft Hong Kong marine deposits (HKMD) with different clay contents. The focus is placed on the influence of the clay content on the stress-strain strength characteristics of the HKMD, including the stress-strain curves, effective stress paths, friction angles, and Young's modulus. The results are discussed and interpreted. New understanding and useful correlations are presented.
