Abstract：The strain behaviors of the stripe reinforced soil with the rigid retaining wall are studied with the large-scale shaking table model test in this paper. The damage of the rigid retaining wall is investigated considering the relative density of the soil，displacement on the wall and characteristics of Fourier spectrum. The test results show that the main region of stress in the strips moves from the potential damage zone to the stable reinforcement zone with the increase of amplitude of seismic wave. The analysis of the strain of the strips show that the damage of the retaining wall begins in the middle of the reinforced area and develops downward gradually. The study of potential fracture plane shows that the form is similar to 0.3 H(H is wall height) which is adopted in the standard，but the area is larger. The relative density of the soil increases with the increasing input PGA(0.1 g–0.3 g) and decreases when the PGA is greater than 0.4 g. The Fourier spectrum of white noise after different seismic waves develops from a single peak to double peak when the seismic wave propagates up. The frequency of the second peak trends to increase when the PGA of wave is not less than 0.4 g.
