In　order　to　deeply　study　the　seismic　response　of　pile-structure　system　and　soil-structure　dynamic　interaction　in　non-liquefiable　sites,　a　large-scale　shaking　table　test　of　dynamic　interaction　of　soil-structure　system　was　carried　out,　and　the　acceleration　seismic　response　characteristics　of　non-liquefiable　sites　and　pile　group　foundation　were　expounded　emphatically　in　this　paper.　Besides,　the　law　of　lateral　deformation　of　soil　and　the　distribution　of　bending　moment　of　pile　foundation　were　analyzed.　The　test　results　show　that　the　acceleration　response　of　soil　and　pile　foundation　is　amplified　and　the　amplification　of　acceleration　is　more　obvious　when　the　soil　is　far　from　the　structure　as　the　0.05g　sine　beat　wave　is　input.　When　0.3g　Wenchuan　Earthquake　seismic　record　is　input,　the　acceleration　response　is　only　magnified　in　the　soil　far　from　the　pile　foundation　and　the　maximum　bending　moment　of　the　pile　is　more　than　60　N•m,　the　bending　moment　amplitude　of　pile　foundation　basically　shows　the　rule　that　the　upper　bending　moment　is　small　(near　the　top　of　pile)　and　the　lower　bending　moment　is　large　(near　the　end　of　pile)　and　the　bending　moment　near　the　soil　interface　has　a　sudden　change.　Besides,　the　acceleration　response　of　superstructure　decreases　to　a　certain　extent　and　the　intensity　of　Arias　decreases　obviously　when　0.3g　Wenchuan　Earthquake　seismic　record　is　input,　and　Arias　of　structures　on　rigid　sites　are　3　to　4　times　larger　than　that　on　soil,　indicating　that　the　energy　dissipation　of　soil　is　obvious.　©　2022,　Editorial　Office　of　Journal　of　Building　Structures.　All　right　reserved.
