Abstract

With the evolution of computer technology in geosciences, finite element modeling can be easily applied to the treated areas by stone columns, which are a method of improving the soil having low geotechnical properties and likely to deform significantly under load action , by incorporating granular material (commonly called ballast) compacted by remounting passes. This numerical modeling is a simple and effective alternative to approach the real behavior of soils reinforced by stone columns, it allows settlement analysis, lateral deformation, vertical and horizontal stresses in order to understand the behavior of columns and soil. It also has the advantage of integrating the settlements of the underlying layers, especially those of least resistance. This paper aims to study the behavior of column groups by establishing the relationship between the columns spacing, columns properties, columns length and the settlement improvement. Based on the finite element modeling of the \ground / Columns\" and taking as a case study the reinforcement of “Bouregreg Valley” ground."""
