Particle Flow Numerical Simulation of Landslip of Loose Slope under Seismic Loading

  • Received Date: 02 Sep 2008
  • The landslip process and law of loose slopes under seismic loading were investigated by using PFC2D(particle flow code in two dimensions) based on the discrete element method.In the numerical simulation,the effect of seismic intensity on the landslip of loose slopes was analyzed by changing the angle of underside due to pseudo-static method,and the numerical simulation results were compared with the exsiting centrifugal test ones.The research results show that the landslip law of loose slopes can be analyzed effectively by a particle flow code model.Under seismic intensities of 5,6 to 7 or 8 degree,landslip scale is respectively about 5%,18% and 45%,and departure from the critical slope is less than 1.0°,1.0° to 2.0° and about 10°,respectively.The numerical simulation results are consistent with the exsiting centrifuge experimental ones.The research provides a reference for the aseismatic design of loose slopes and the evaluation of river and road barrage.
