Abstract：The deformation and the influence factors of the wrap reinforced retaining wall located on the soft soil foundation was carried out by the method of centrifugal model test and numerical simulation with FLAC2D. The centrifuge model test showed that the lateral deformation of the wrapped reinforced retaining wall was small and the wrapped reinforced retaining wall acted as a traditional panel. The effects of length and vertical spacing and stiffness of geosynthetics on the deformation of the retaining wall were analyzed in the numerical simulation with FLAC2D and the centrifugal model tests respectively. The results of the numerical and experimental study showed that the vertical spacing of geosynthetics is the most significant factor influencing the deformation of the retaining wall，and these three parameters should be controlled in a certain scale in the actual projects.
