Étude géologique, géotechnique et dimmentionement d’un tronçon de métro passant sous des blocs pédagogiques (exstension Ain Naadja-Baraki , Alger)

Abstract

The metro line, which is concerned by our study, is under study and has not yet reached the stage of realization, it passes under the city of Beraki to a length of 200 m. The objective of this work focuses on the geological and geotechnical study f this tunnel planning,from the description of this project and the geological context through a geological interpretation of the Algiers region, the water-climate framework and the hydrology of the study area. The geotechnical analysis of the results of the on- As well as the results of laboratory tests conducted on samples recovered by basic drilling. The results are used to suggest the correct and accurate dimension and verify it, to ensure the lift and stability of our long-term usiness.These results were also used to calculate and predict possible settlement and to model a structure using the PLAXIS 3D software
