ABSTRACT

Knowledge of the mechanical behaviour of deep-ocean sediments is based on data from soils from a limited number of sites, the majority being in the North Pacific. Available data for these soils generally consist of index properties, compressibility and permeability. This paper presents rare data from an Atlantic site and examines them within the Critical State framework. The effects of soil structure on the behaviour of the deep-ocean sediments are investigated and a numerical model developed for structured clays is applied to the test data, showing that such models can simulate the behaviour of some deep-ocean sediments.
