ABSTRACT: The purpose of this paper is to present an analytical solution of multi-step reinforced-soil slopes due to static and seismic loading. This solution is based on the kinematic theorem of limit analysis and on the quasi-static approach and concerns homogenous cohesionless soils that are expected to deform plastically, following the Coulomb yield criterion. For the implementation of this methodology, a computer programme has been designed and representative examples are shown. With this programme, different types of potential failure mechanisms are studied and the most critical ones are used for the final design. Finally, multi-step and one-step reinforced slopes with the same height and soil mechanical characteristics are analysed and compared and conclusions are derived concerning their stability and the amount of the reinforcement that is necessary to prevent failure.
