ABSTRACT: The authors proposed a simplified method based on the isotache concept by using a compression curve and relationship between the consolidation yield stress (preconsolidation pressure) and the strain rate. The latter is expressed by an equation with three isotache parameters. The isotache parameters commonly determined for the Osaka Bay clays retrieved from various depths up to 300 m below the seabed are applicable to worldwide clays with various characteristics.

RÉSUMÉ: Les auteurs ont proposé une méthode simplifiée fondée sur le concept isotache en utilisant une courbe de compression et la relation entre la pression de préconsolidation et la vitesse de déformation. Celui-ci est exprimée par une équation à trois paramètres isotache. Les paramètres isotache souvent déterminée pour la baie dOsaka argiles extraites de différentes profondeurs allant jusqu'à 300 m sous le fond marin sont applicables aux argiles à travers le monde avec des caractéristiques différentes.
