Abstract
A multiphase model for assessing the macroscopic behavior of earth structures reinforced by two-dimensional inclusions in the context of elastoplasticity is presented and incorporated into a finite element based numerical tool with an appropriate return mapping algorithm. The obtained numerical tool is applied to the stability analysis of an axisymmetric reinforced soil-structure and a parametric study is then considered for different interaction conditions between the soil and the reinforcing membranes, corresponding to a perfect bonding assumption, a perfectly smooth interface and an intermediate case. The stability factors quantified by this study for the different cases are then compared to those obtained by a yield design analysis.
