AB  - A numerical analysis of soil behaviour around pressuremeter probe, based on the generalised Prager’s model associated to the Drucker and Prager Criterion is presented. First of all, the soil behaviour law is described, based on the analytical representation of the stress-strain curves obtained with triaxial tests. This show, how the parameters of the generalised Prager model with a large number of elastoplastic slip elements associated in series can be identified. Secondly, the effect of these parameters on the simulated curve and the principal stresses path around the probe are analysed.
