The development and evaluation of a constitutive model for the prediction of ground movements in overconsolidated clay

Abstract: The stress—strain response of overconsolidated clay depends both on its current state and on the loading history followed to reach that state, in particular the relative directions of the current and previous loading paths. A constitu-tive soil model is developed which predicts this behaviour by allowing elasto-plastic deformations controlled by two nested kinematic hardening surfaces inside a conventional Modified Cam-clay state boundary surface. This relatively straightforward model requires only eight para-… Show more

“…the shear modulus at very small strains and κ * is the initial slope of the isotropic swelling line in ln v − ln p' space. The value of G' e can be assumed to vary with p' and overconsolidation ratio, R o according to the relationship proposed by Viggiani and Atkinson (1995) (Stallebrass and Taylor, 1997):…”
