Abstract Based on fundamental theory of limit analysis of plasticity，the upper bound procedure is employed in limit analyzing the stability of soil slope reinforced by uniformly distributed geogrid. It obtains expression of the upper bound of critical height and stability number for reinforced soil slope，which are compared with non- reinforced soil slope. Eventually，the effects of slope angle，surface inclination angle，frictional angle of soil and geogrid tensile strength on stability number are analyzed for retaining soil slope.
