In this paper the enriched radial basis point interpolation (RPIM) method is implemented for the elasto- plastic analysis of reinforced soils. Enrichment with polynomial terms increases the accuracy and reproducibility of the method. In present study the reinforced soil is descritized into soil, reinforcements and interface layer. Displacement field in each part is constructed by the RPIM. Final system of equations is obtained by the substitution of generated displacement field into the weak form of governing equations. The elasto-perfectly plastic behavior is assumed for soil, reinforcement and interface layer. The application of linkage element concept provides the possibility of slippage modeling in the interface layer. Based on the derived equations, a computer code has been developed and its validity is investigated by solving some examples at the end of the paper.
