The　aseismic　behavior　of　permanent　soil-nail　supporting　system　is　investigated　by　shaking　table　tests　with　a　scale　factor　of　1/12.　During　the　tests,　dynamic　characteristics　and　rules　of　the　slope　are　investigated　with　different　supporting　conditions,　such　as　nail　inclination,　nail　length　and　nail　space.　In　vibration　condition,　the　lateral　displacements　mainly　occur　at　the　abdomen　of　the　slope,　and　the　displacements　at　the　crest　and　foot　are　relatively　small.　The　shape　of　maximal　function　belt　is　polygonal-shape　and　the　maximal　function　belt　is　located　in　the　foreside　or　middle　part　of　the　soil　nailing　area.　The　response　accelerations　in　the　middle　of　the　slope　and　at　the　bottom　is　very　close,　but　the　response　acceleration　is　relatively　larger　at　the　top　part.
