| Abstract: | In this paper,the stability of slopes reinforced with geosynthetics is analysed within the framework of the pseudo-static approach under the seismic loading only for the translational failure mode.Calculations are conducted by applying the kinematic theorem of limit analysis,and each analytical expressions are derived that enable one to conveniently calculate the closed-form solutions of the reinforcement force required to prevent failure and the yield acceleration of slopes subjected to earthquake loading. |
