    • Abstract
  • Centrifuge tests on a geosynthetic-reinforced slope are performed to investigate its deformation modes, macroscopic mechanical properties and particle movement in the soil-geosynthetic interface. Through a comparison between the centrifugal test results at 20g and the static model test results, the macro-mesoscopic mechanism of the same size reinforced slope under different stresses is further analyzed. The results show that the wrapped-reinforced sand slope under different stresses has different failure modes. Under high stress state, the peak friction of the interface is greater than the tensile fracture strength of reinforcement materials. But under lower pressure, the tensile fracture strength of reinforcement materials is greater than the peak friction of the interface. Different stress states may significantly influence the interaction in the soil-geosynthetic interface. This study has a positive significance for further understanding the failure mechanism of the wrapped-reinforced sand slope.
