In this paper, a new hypoplastic model for K0 consolidated soft clays is presented. The enhanced model is characterized by a small number of parameters, adding two parameters to the original model, whilst significantly improving model predictions of undrained stress paths of K0 consolidated soils. However, the calibration procedure remains simple – model can be calibrated using K0 consolidated triaxial tests and oedometer only. It is demonstrated that the model predictions compare well with element test experimental data. The validation of the model involves large scale boundary value problem simulations incorporating very large deformations, in this case retrospective simulations of centrifuge test of spudcan installation. The enhanced model shows better performance compared to a parent hypoplastic model.
