Prospection géophysique et caractérisation géotechnique pour l’étude de la faisabilité de l’implantation d’un projet d’aménagement dans L’UFAS. Cas de campus EL BAZ.

Abstract

In order to build a rest home within the University of Setif-1- Campus el Bez, we have taken in hand to make the preliminary studies of the soil where the project will be established. With this, we first made bibliographical research on the geology of the region to deduce the lithology of the layers of our subsoil. Geotechnical studies were done on the site, samples were retrieved and analysed at the laboratory of the Institute of Architecture and Earth Sciences. Geotechnical test batteries were able to reveal the mechanical and physical characteristics of our soil. It was thus deduced that the clays found were moderately plastic and had a shrinkage capacity swelling, which is a big problem in any project. Geophysical studies followed mainly the seismic refraction, from which we could deduce the speed of the P waves in our soil, but also have a section of thesubsoil and the thicknesses of our geological layers. Finally, we have presented plausible solutions to our main problem, being swelling clays. These solutions are based mainly on the adaptation of the foundations and their depth, protection against vegetation, the choice of a structure for the building ... etc. The choice of one or more of them will be on bail of funding and technical feasibility. Thus, precautions will be taken for the beginning of our project which will avoid having future accidents that could affect the structure of the building, and the people who will be there, not to mention the huge costs that could be generated.
