Abstract: A series of true triaxial shear tests of Guangzhou structured natural silty clayey samples are tested with consolidated undrained shear with an equivalent stress ratio. A new parameter, called equivalent strain ratio, b , is introduced in this paper, in order to characterize the mechanical properties of this structured silty clayey samples under similar conditions.
