    • Abstract
  • Based on the finite element model of sandy soil slope, the stability of sandy soil slope is studied. The results show that superposition method of coupling of earthquake and groundwater in codes is very limited. The evaluation index of permanent displacement is more accurate than safety factor. With the increase of groundwater, shear strain decreases, and the maximum value appears at the bottom of the slope which is destroyed easily, and the effective stress at the bottom of the slope decreases obviously, which is disadvantage for the stabilization of the slope. With the increase of groundwater level, the maximum axial force and the maximum bending moment show a decreasing trend, and the soil nailing axial force of the slope has the maximum value near the bottom of the slope. Based on the comparison between shaking table test and the numerical simulation, the accuracy of the numerical simulation results are verified.
