In　order　to　investigate　the　influences　of　parameters　on　aseismic　behavior　of　soil　nailing　system,　some　shaking　table　tests　are　designed　and　carried　out.　Dynamic　characteristics　of　the　soil　nailing　system　with　different　parameters　(such　as　nail　inclination,　nail　length,　nail　space)　are　studied.　It　is　found　that　the　soil　nailing　system　has　good　aseismic　behavior.　The　maximum　lateral　displacement　mainly　occurs　at　the　abdomen　of　the　slope　during　the　tests,　but　the　displacements　at　the　crest　and　foot　are　relatively　small.　Increasing　the　soil-nail　obliquity　will　increase　the　lateral　displacement,　but　increasing　the　length　or　reducing　the　space　of　soil　nail　will　minish　the　lateral　displacement.　The　shape　of　the　maximal　function　belt　is　polygonal-shape,　and　the　maximum　function　belt　is　located　in　the　foreside　or　middle　part　of　the　soil　nailing　area,　which　is　not　the　sliding　plane　appearing　under　vibration　condition.
