Étude Géologique Et Géotechnique De l’Instabilité Au Niveau De Tarzoust El Milia - Wilaya de Jijel -

Abstract

In order to avoid problems of instability and thus ensure the sustainability of any project, it is essential to proceed to the recognition of the geotechnical and geological characteristics of the layers forming the base of the project.Located in the secondary agglomeration of Tarzoust El Milia, the study site was affected by a series of destabilizing land movements. The stable natural terrain, covered for the most part by vegetation (scrub, forest), does not present any notable manifestation of instability. Through this research work, we have tried to understand the factors responsible for the instability and its evolution in recent years, despite the installation of different means to stabilize the site. For that, we took again the various results obtained by the various geotechnical studies in particular the study of stability carried out in 2010. We also made a topographic study in order to have a confirmation of the continuous evolution of the movement
