Etude et géotechnique de la stabilité du versant de 80 logements « EL BAHIA commune d’AIN KEBIRA »Sétif.

Abstract

The objective of this work is to make a geological and geotechnical study, and the study of reinforcement of a landslide that affected the threat upstream side block No. 01 of 80 RHP housing, following all the steps necessary this study from the geomorphology, geology and hydroclimatology, geotechnics, via the stability study. The trigger source of the latter is the result of a combination of unfavorable factors of predisposition and triggers. Primarily geological heritage, geography and the type of soil and two other factors that contribute to instability, water and man can explain the instability. Analysis of this slip is conducted by a software : Talren 04 to materialize the potential fracture surfaces .From this analysis we determine the reinforcement solution adopted based on a technical and economic study.
