摘要：

This paper concerns the study of the over-consolidation state of a marine sediment extracted from the continental slope in the Gulf of Guinea. Special attention was devoted to the physicochemical phenomena. The study was carried out 1) at a microscopic level using the theory of the diffuse double layer [6, 8, 12] and 2) at a macroscopic level using an elastoplastic model considering the suction as a stress state variable [1]. These models have provided a physical explanation as well as an adequate description of the phenomenon of over-consolidation.
