Flow Characteristics of Clays

open access: yesSoils and Foundations, 1973
ABSTRACT Based on a critical review of the available data in creep tests previously published by many investigators, a new concept of flow envelope is presented and substantiated for normally consolidated clays. It is shown that the flow envelope is expressed by a simple equation irrespective of the type of clays, water content, drainage condition ...
