In this paper, the seismic stability of slopes reinforced with geosynthetics is analysed within the framework of the pseudo-static approach.Calculations are conducted by applying the kinematic theorem of limit analysis. Different failure modes are considered, and for eachanalytical expressions are derived that enable one to readily calculate the reinforcement force required to prevent failure and the yieldacceleration of slopes subjected to earthquake loading. Several results are presented in order to illustrate the influence of seismic forces onslope stability. Moreover, a suitable procedure based on the assessment of earthquake-induced permanent displacement is proposed for thedesign of reinforced slopes in seismically active areas.
