The kinematic theorem of limit analysis is used to evaluate the amount of reinforcement necessary to prevent collapse of slopes. The results are also applicable to some failure modes of reinforced walls. Calculations were performed assuming uniform and linearly increasing distributions of reinforcement strength through the slope height. The computational results
are presented in charts, which can be used in design. The seismic influence is substituted with a quasi-static horizontal force. While such an approach ignores the acceleration history and does not allow any insight into the behavior of a structure, it is being routinely used in practice, and the charts are off€ered as a design aid to determine the amount or strength of reinforcement. The length of reinforcement was also calculated, based on collapse mechanisms which include rupture in some layers and pull-out in others. It was found that the distribution of reinforcement with variable spacing, to match the triangular distribution of  "smeared" strength, is more economical than a uniform spacing. Uniform spacing requires longer rein-
forcement and larger strength.
