Abstract
It is well known that geomaterials exhibit quasi-elastic stress-strain behaviour at small strains. The stiffness in this small strain region is herewith termed as pseudo-elastic modulus. A laboratory investigation was performed into the pseudo-elastic modulus of reconstituted clays by considering some influencing factors such as consolidation history, drained creep, loading condition (i. e. strain rate, monotonic and cyclic loadings). On the basis of results of a series of undrained triaxial test performed, the variation of the pseudo-elastic modulus with each influencing factor was successfully expressed in a quantitative fashion by examining the e-logp' relationship of the clays when subjected to both consolidation and swelling.
