Marine geotechnics is one of the most difficult specialties and is part of coastal engineering. The geotechnician is interested in soils as these are the main element of the context in which the stability of a structure will be designed. The methods of improvement of vibroflotation (VF), dynamic compaction (DC) and the pre-loading took a scale in Algeria these last years, they are applied at the port of DjenDjen in Jijel province, object of our study, in the framework of its extension and its development, in order to improve the support soil which will receive the foundations of the protections structures and the container terminal in caissons. The main objective is to establish numerical studies of the stability of the protection structure realized on the improved soil which was itself taken into consideration in the modelling, while respecting also the real phasing of construction of this structure. However, soil improvement was checked before and after treatment to verify its influence on the stability of the harbour structures.
