The reinforcements used in reinforced soil walls are usually ribbed steel strips, but in aggressive environments, geosynthetic straps are preferred due to their non-corrodible properties. However, the synthetic reinforcement presents a complex behaviour due to their extensibility and leads, according to their stiffness, to different behaviours of the structures. An experimental study, which concerns laboratory pull-out tests, enabled us to define and to compare the interaction parameters at the soil/reinforcement interface of the synthetic and metallic strips. The use of these parameters in the numerical calculation codes allows to improve the modelling and the inherent safety of such reinforced soil structures. This paper presents a parametric study of reinforced soil wall by two-dimensional finite difference modelling. It highlights the importance of each parameter and then allows the authors to provide a better structure design.
