Abstract

A micromechanistic theory is developed on the basis of variational principles to facilitate the interpretation of experimental data relating the stress-strain behavior of a clay soil to its fabric and water retention characteristics. This formulation yields a stress-strain expression with terms to characterize the void ratio and particle orientation distribution, as well as certain deformation parameters, one set of which is an empirical function of the soil-water potential. The resulting theoretical relationship is applied to study the response of five representative fabric samples prepared from a slurry with two different chemistries and consolidation stress paths.
