On the calibration and application of the NorSand model


Advanced constitutive models that are capable of reproducing different aspects of sand behaviour have been an object of study for many years. The models developed in the critical state soil mechanics framework, with a formulation based on the state parameter, are of particular interest as they can predict the sand response over a full range of stresses and void ratios. This paper briefly introduces a generalised 3D formulation of the NorSand constitutive model, as one of the models with such capabilities. The model is attractive for use due to its relative simplicity and a small number of model parameters that can be obtained from conventional laboratory testing. The calibration of the model presents and discusses the process of integrating laboratory and field data on the example of natural Dunkirk sand. The performance of the model is finally validated in the finite element analysis of a laterally loaded pile, by favourable comparison of numerical results against field measurements of pile response to lateral loading.
