Abstract

The Pastor-Zienkiewicz constitutive model, developed in the late ’80s in the framework of Generalized Plasticity Theory, is suitable to reproduce many features of frictional materials, both in drained and undrained conditions, with particular attention to the modelling of the volumetric behaviour of dilatative sands. This research deals with its applicability to describe the response of natural sands, silts and very silty clays, forming the subsoil of Venice and its lagoon. With this aim, results of anisotropically-consolidated, drained, triaxial compression tests are compared with the prediction provided by the Pastor-Zienkiewicz model, which has been recently implemented in a FE code using a new implicit scheme.
