ABSTRACT: Results from piezocone tests in sensitive clay from Haney BC are interpreted using a modified analytical model based on spherical cavity expansion theory and critical state soil mechanics. The solution allows the evaluation of the undrained rigidity index which in turn provides the profiles of undrained shear strength and yield stress. The yield stress ratio is expressed in three separate formulations using net cone resistance, excess porewater pressure, and effective cone resistance. When compared together, this trio is useful in the identification of sensitive clays from insensitive clays.
