Abstract
The Prevost's model is currently used to model cyclic behaviour of soils especially in earthquake engineering. The original model is able to capture the main features of cyclic behaviour: pore pressure build up and plastic deformation accumulation. But accurate modelling of laboratory tests requires improvements. Enhanced models exist but require a lot of parameters that make them cumbersome for practical purpose. A suction caisson, part of a tripod offshore foundation for wind turbines is modelled. Possibilities of the Prevost's model are highlighted compared with a classical Drucker-prager model.
