Abstract	Le présent article constitue une contribution à l’étude des causes, à la caractérisation et à la modélisation numérique aux éléments finis du glissement de terrain affectant le versant côtier au bord de la mer Méditerranée à proximité du centre-ville de Tigzirt (Algérie). Ce versant est caractérisé par une pente relativement faible (de 13° à 15°), composée de deux formations géologiques principales (un substratum marneux surmonté par des dépôts quaternaires récents). Plusieurs facteurs ont agi conjointement et expliquent l’activité du glissement de terrain de Tigzirt: il s’agit de l’effet des contextes géologique, morphologique et hydrogéologique du site combiné à des facteurs déclenchant d’origines diverses (anthropiques, climatiques et sismiques). Le glissement de terrain est caractérisé par une surface de rupture plane qui mobilise un mécanisme de déformation global en translation vers la mer.This article is a contribution to the study of the causes, characterization, and numerical modeling, using finite elements, of the landslide affecting the coastal slope at the edge of the Mediterranean Sea near the city center of Tigzirt (Algeria). This slope is characterized by a relatively low inclination (13°–15°) and composed of two main geological formations (marly bedrock overlain by recent Quaternary deposits). Several factors have acted jointly and explain the activity of Tigzirt landslide: it is the effect of geological, morphological, and hydrogeological site contexts combined to triggering factors of various origins (human, climatic, and seismic). The landslide is characterized by a planar failure surface, which involves a global translational deformation towards the sea.
