Behavior of Marine Sand-Clay Mixtures under Static and Cyclic Triaxial Shear

Abstract

In situ Indian Marine soils occur as mixtures of sand and clay in widely varying proportions. Their engineering behavior has not been comprehensively and systematically studied. An experimental program on reconstituted Indian marine soils having different proportions of sand and clay was undertaken. The study comprised one dimensional consolidation tests and static and cyclic triaxial tests. This paper presents the results of this study and offers an interpretation of the behavior based on effective void ratio (EVR), a new parameter defined as the ratio of volume of voids to the volume of effective soil fraction. Experimental results indicate a roughly unique
