Geotechnical Valorization of the Berhoum Area (Algeria) Geological Map for Preparing a Geotechnical Map for Construction

This study dealt with the followed methodology and the obtained results of a geotechnical valorization test for the Berhoum zone geological map (ex-Souk Ouled Nedjaa) in order to prepare a geotechnical map for construction using a geographical information system (GIS). The basic document was the existing geological map. The geological units have been characterized from a geotechnical view point. From the existing data, each geological unit was as much as possible represented by a number of average physical and geomechanical parameters. The homogeneity of the response made it possible to highlight the geotechnical units and establish a geotechnical classification of the different terrains. The geotechnical map for construction was the ultimate result of this study.
