Pressiometric sounding applied to the recognition and geotechnical study of the foundation soil of an industrial building: Case of the crushing center in Jorf Lasfar (El Jadida -Morocco)

Abstract

The problem of recognizing the spatial variability of a site is nowadays more important, especially in a greater way, in particular because of the extension of the urban zones as well as industrial areas. The campaign of the recognition of the site of study is constituted by the drill B47/2 and the Menard pressure meter, the reconnaissance took place during one month and ten days, in the industrial park Jorf Lasfar industrial park, Moulay abdallâh commune. The recordings of drilling parameters or pressure tests offer the possibility to locate the the possibility of locating the heterogeneities of the environment during the execution of a drilling at a very small scale, but the scale, but the results obtained are more usable within the framework of the of foundations and their interpretation can be particularly delicate because of the inter because of the interdependence of the various parameters and factors influencing the pressure pressiometric response. The objective was to exploit in a general way the data and the results of the pressuremeter tests, in order to improve the image of the subsoil and better know the global risk by finally deducing a richer image of the site qualitatively and quantitatively and the foundation of this project.According to the previous study and our current study, the formations encountered in the study area have study area have very good geotechnical characteristics, which make them excellent foundation bases. The permissible working rate in sandstone limestones can reach higher values. The foundation system that can be adopted in these formations for the majority of the structures. The foundation system that can be adopted in these formations for the majority of structures consists of isolated square or rectangular footings. The settlements are not to be feared because they are reduced to the elastic deformations of the massif.
