ABSTRACT: The city of Constantine is located in the Tell North area, occupying a 15 Km2 area limited by varied reliefs, in certain cases truly steep. The region altitude varies between 300m (riverbeds level) and 800m at the conglomerate beds summit. The slope inclination varies from 12º to 35º with the exception of the Rhumel river canyon which has a cliff type morphology. The geology of the region of Constantine is complex due to a tectonic structure dominated by the presence of nappes. It is characterized by a neritic sedimentation of limestone and marls up until the Cretaceous period, followed by a flysch type sedimentation (conglomerates and sandy clays) in the Tertiary and also by a shallow tectonic style characterized by the presence of flexible folds affected by numerous faults. This study describes the stability analysis of a retaining wall supporting the main road line of a highway in Constantine using finite element program.

RÉSUMÉ: La ville de Constantine se trouve dans la zone Nord d'Atlas-Tellien, et elle s'étend sur une superficie d'environ 15 Km2 limitée par des reliefs très variés, dans certains cas exceptionnellement accidentés. L'altitude de la région varie entre 300m (niveau cours d'eau) jusqu'à 800 m au sommet des buttées conglomératiques. Les pentes des versants varient entre 12° à 35°, ued Rhumel, où la morphologie est escarpée. La géologie de la région constantinoise est extrêmement compliquée à cause de sa structure tectonique dominée par des nappes, caractérisé d'une part, par une sédimentation néritique marqué par le dépôt des calcaires et des marnes jusqu'au Crétacé, puis de type flysch (poudine autoroute dans la ville de Constantine en utilisant la méthode des éléments finis.
