Abstract
Large-scale reinforced earth retaining wall model test has been Designed and completed. The model size is 3.0mχ0.85m χ2.0m(lengthwidthhigh) Slope angle is 70º, Fill with the use of red sandsχtone construction site preparation materials By entering a different amplitude and frequency of the sinusoidal load, to discuss the law of Dynamic characteristics of the model wall and fatigue life under the repetition load. The results showed that, the fatigue life has a linear relationship with the stress amplitude of three reinforced structures ,the logarithm of fatigue life changes with the stress amplitude sensitivity of Gabion reinforced earth retaining wall is low than Geogrid reinforced retaining wall does. The results help to reveal the instability mechanism under cyclic loading, and provide a useful reference for designing the reinforced retaining wall engineering.
