MODELISATION STATISTIQUE DES PROPRIETES PHYSICO - MECANIQUES DES MATERIAUX SABLO GYPSO-CALCAIRES DE LA REGION DE OUARGLA

Abstract

Gypsum-limestone crusts Tuffs are considered like the first road on geotechnical materials at Algeria southern Saharan zones. These local materials are widely used for those economic developments in these regions. Some experimental tests are usually used by the engineers for identification. These analysis processes take lot time. However in some constructions, quick knowledge performance of these materials is essential for a successful project, especially in terms of deadlines. This is why finding a way to reduce the analysis time is important. The aim of this search is to find some models for predict certain properties of these materials. Then reduce the analyses time. The statistical method modeling was used. It is based on classical statistical tools (single, multiple and polynomial regression). The result show that some of the models built are acceptable, but still require improvements applied to beings with great precision.
