Abstract

Confining of granular materials remains a very interesting engineering practice to perform civil and / or geotechnical engineering works. In this paper, the analysis of the mechanical behavior of technical fabric- confined sand models in order to design bearing provisional and / or permanent structures is exposed. A composite structure, made of local materials (technical fabric and sand) and exposed in previously achieved works, belongs to a context of sustainable development, when a design and an analysis, for the first time, of a monostory building for use in inaccessible areas were carried out (i.e. Sahara). As a new perspective, many other applications (geotechnical) are considered, such as retaining wall structures, structures for protection against impacts and linear structures applied in rural road traffics. For this purpose, an experimental analysis was conducted on specimens made of technical fabric-confined sand in order to determine the mechanical properties of studied structure; This is followed by mathematical treatment of experimental results, leading to mathematical regressions development which can be injected into a numerical Finite Element Method analysis (ANSYS Code), analyzing the mechanical behavior of the indicated above structure.
