Abstract

This paper presents explicit expressions for the principal effective stresses generated around a cylindrical cavity expanded in plane strain and undrained conditions in Modified Cam Clay. The assumption made in the present analysis is that Poisson’s ratio v′ remains constant throughout the shearing process. Theoretical expressions are applied to the simulation of a cylindrical cavity expansion test in Ko normally consolidated remoulded Boston Blue Clay modelled as Modified Cam Clay. The results, which are compared to those obtained by assuming that the shear modulus \( G^{{\prime }} \) remains constant, show that the two approaches are quite similar.
