The　seismic　behaviors　of　piles　retaining　the　slopes　are　studied　by　means　of　large-scale　shaking　table　tests.　The　model　slope　is　installed　into　a　model　box　with　a　length　of　3.7　m,　width　of　1.5　m　and　height　of　1.8　m.　The　sizes　of　model　and　prototype　slope　are　designed　by　using　the　similar　principles　with　a　scale　factor　of　1:20.　Similar　materials　are　made　up　of　the　standard　fine　sand,　gypsum　powder,　talc　powder,　glycerin　and　water,　and　the　specimens　are　reconstituted　with　density　of　2.5　g/cm3.　Three　different　kinds　of　seismic　waves　are　input　to　study　the　dynamic　response　stabilizing　piles　by　increasing　the　amplitude　of　input　seismic　waves.　By　monitoring　the　soil　pressure　after　the　piles,　the　acceleration　and　displacement　response　of　the　slope,　the　distribution　of　the　soil　pressure　behind　the　piles　and　the　seismic　performance　of　the　piles　are　studied.　This　research　provides　a　good　foundation　for　seismic　design　of　stabilizing　piles.
