In　this　study,　the　shaking　table　tests　were　conducted　to　investigate　the　seismic　response　of　a　high-filled　reinforced　embankment　supported　by　pile　and　slab　structure　on　slope　terrain.　The　macroscopic　damage　phenomena　of　the　test　model,　acceleration　response,　displacement,　dynamic　earth　pressure　and　bending　moment　of　the　pile　were　thoroughly　examined　and　discussed.　The　results　revealed　that　the　high-filled　subgrade　reinforced　embankment　had　a　favorable　seismic　stability.　Despite　the　absence　of　collapse　after　1.2　g　seismic　load,　there　was　a　certain　extent　reduction　in　structural　resonance　frequency.　The　dynamic　earth　pressure　behind　the　pile　initially　increased　from　the　top　to　the　bottom　and　subsequently　decreased　near　the　soil　boundary.　However,　with　the　seismic　magnitude　increasing,　the　peak　value　of　the　earth　pressure　near　the　pile　bottom　gradually　increased　due　to　pile　rotation.　The　bending　moment　of　the　pile　presented　a　bow-shaped　distribution.　The　acceleration　exhibited　a　notable　amplification　effect　along　the　height　of　model,　while　the　horizontal　acceleration　amplification　factor　decreased　with　seismic　magnitude.　Furthermore,　the　time–frequency　domain　characteristics　and　energy　distribution　of　the　model　were　investigated　using　the　Hilbert-Huang　Transform.　This　study　provides　a　theoretical　basis　for　the　design　of　supporting　structures　for　high-filled　subgrades　in　high-intensity　earthquake　areas.　©　2024
