A numerical model simulating the seismic response of gabion support-slope systems was established based on the dynamic analysis module of the finite element numerical simulation software ABAQUS to study the seismic stability of gabion support-slope systems,and the model was verified with shaking table test results.The parameters that may affect the seismic stability of the gabion support-slope system were also analyzed.The results show that the displacement time-history curves of the gabion units under seismic action follow a similar pattern:the displace-ment abruptly reaches the peak at the peak acceleration and then gradually settles down.After-ward,the displacement gradually increases along the elevation,and the maximum displacement increase occurs at the bottom and top gabion units.The key to controlling the displacement of gabion units lies in the reduction of the relative misalignment between adjacent gabion units and the deformation of gabion units under seismic action.Increasing the elastic modulus of gabion units,raising the friction coefficient between gabion units,and decreasing the relative length of steps can notably enhance the stability of the gabion support-slope structure.
