Abstract

A simple macromechanics based strategy is used to arrive at the description of consolidation of clayey soils. In particular, an isotropic consolidation, as a tool for inferring the basic material parameters of various phenomenological models, is discussed here in conjunction with the modified CAM clay model. The paper shows a rather poor ability of the classical CAM clay model to characterize the process of consolidation. In view of this shortcoming, two principal modifications to the existing CAM clay model are proposed to improve the mechanical modeling of clayey soils. A number of examples are presented to evaluate applicability of the improved model.
