The scope of this paper is the analysis of a piled embankment reinforced geosynthetic with discrete element method andsoil model at the microscopic level. The vertical stress distribution, load transfer mechanism, efficacy, differentialsettlement and tension in geosynthetic were chosen for comparison and interpretation of results. The contribution oftensioned membrane effect by geosynthetic reinforcement to load transfer mechanism is elucidated through the numericalanalysis, which is generally neglected in the most current design procedures. Additionally, a new analytical approach wasproposed to analyze the load-deflection behavior. This method is the results of the combination of the tensioned membranetheory and soil arching theory, thereby providing a more suitable design approach and believed to be a useful tool forengineers in designing the soil-geosynthetic system. The validity of the analytical method is compared to the numericalresults by using the discrete element method. Thus, the results of this study are intended to provide some guidelines fordesigners and to bring insight about the interacting mechanisms into the design process.
