Description

Based on results of triaxial or torsion cyclic loading tests on a variety of soils containing organic matters such as highly organic soil or organic clay obtained from Hokkaido or Akita prefecture, empirical equations for elastic shear modulus G0 and reference strain γr are proposed. Density of soil particles, which exhibits good correlation to ignition loss, is introduced as a parameter reflecting content of organic matter in the equation for G0. In case of saturated soil, this equation is roughly consistent with other researchers’ equation proposed so far by parameters being replaced into water content. Based on a relationship between γr and G0 derived by formula of Hardin-Drnevich model, the empirical equation for γr is successfully expressed as a function of water content and consolidation stress. Compared with prediction from equations proposed, test results fall in a range of 0.7 to 1.5 times for G0 and of 0.5 to 2.0 times for γr.
