Axisymmetric transient modelling of a wind turbine foundation in cohesionless soil using the prevost's model

Suction caissons are more and more used for offshore foundations. This paper deals with the cyclic modeling of suction caissons using the Prevost's model. The case study is a 8m large diameter caisson embedded in dense No. 0 Lund sand. Parameters for the model are calibrated using drained triaxial tests. A parametric study concerning the influence of the constitutive law, the skirt length and permeability is carried out
