%X :Finite element numerical analysis was employed to analyze the horizontal displacement and  vertical displacement of reinforced earth-retaining wall embankment as well as the  vertical stress of the embankment base all  under self-weight. By adopting different incentive accelerations, the acceleration amplification and  the horizontal displacement of embankment was researched. Results show that: under  self-weight load, the stress of the embankment bottom distributes in a curve shape; maximum vertical displacement occurs in the center of embankment; and horizontal displacement distributes in a convex shape along the height. The greater the incentive peak acceleration is, the more obvious the acceleration amplification effect is. As incentive acceleration increases, variation of  horizontal displacement intensifies. There is an optimal <i>R</i><sub>inter</sub> value in different embankments.
