Abstract|ملخص البحث

The geotextiles is the synthetic, permeable tablecloths, used in association with soil to improve their mechanical and/or hydraulic features. These materials are of current use in domains very varied. However, the functional life span of a geotextile woven or non woven can be shortened by a Clogging, either physical or biologic. A survey of the behavior in filtration of the soilgeotextiles system has been achieved in a specialized laboratory (LTHE, ex.LIRIGM,UJF,Grenoble) while using the sand of Ali Oum (Algeria). In this communication, we are going to present an experimental approach aiming to landing to the problems of washing/clogging in the hydraulic application (filtration and/or drainage). It enabled us to check the behavior of the sand of Oum Ali which showed an internal stability. This stability supports the formation of vaults upstream of the filter and ensures thereafter; integrity of its structure and a good behavior of the sand-geotextile system. The mechanism of filtration by the geotextile ones (woven, non-woven materials) is a very complex phenomenon, and depends on several parameters related on the type of ground in contact, the type of geotextile used, and the hydraulic conditions of the medium. Key-Words: Filtration, Geotechnic, Geotextile, Clogging, Washing, Sand of Oum Ali.
