The　geological　structure　of　the　Three-rivers　Basin　is　complex,　with　active　tectonic　movements　and　frequent　earthquakes,　resulting　in　fragile　geological　circumstances,　frequent　geo-hazard　incidents,　and　the　emergence　of　significant　hazard　cascades.　Multiple　earthquakes　lead　to　frequent　landslide　disasters.　Bedding　rock　and　debris　landslides　are　common　disasters　that　threaten　the　Three-rivers　Basin＇s　infrastructure　construction.　In　this　study,　we　took　the　＇Xiaguiwa＇　landslide　as　an　example　and　established　shaking　table　models　of　bedding　rock　and　debris　slopes.　The　Arias　intensity,　improved　marginal　spectrum　multi-peak　slope　damage　identification　based　on　Hilbert-Huang　transform　(HHT)　and　Standard　spectral　ratio　(SSR)　were　used　to　analyze　the　seismic　damage　evolution　of　the　model　slope　and　the　influence　of　the　accumulation　layer　on　seismic　energy　transfer.　The　results　show　that　seismic　tension　leads　to　damage　in　the　top　accumulation　layer　of　the　debris　slope.　The　damage　to　the　bedding　rock　slope　first　appeared　at　1/4　elevation　of　the　slope　surface　due　to　buckling.　Then,　shear　deformation　occurs　at　the　trailing　edge　and　expands　downward　along　the　structural　plane.　This　process　co-occurs　with　the　depression　at　1/2　elevation　of　the　slope.　The　accumulation　layer　has　different　effects　on　the　seismic　energy　of　different　elevations,　and　its　influence　on　the　seismic　energy　of　low　frequency　(40　Hz)　is　more　significant.　The　damage　evolution　of　bedding　rock　slopes　can　be　segmented　into　four　stages:　(1)　slight　subsidence　of　rock　layers　stage,　(2)　rock　bending　and　trailing　edge　cracking　stage,　(3)　slope　waist　depression　and　uplift　surface　fracture　stage,　and　(4)　shear-fracturing　and　the　low-position　shear　out　stage;　That　of　debris　slopes　can　be　segmented　into　three　stages:　(1)　accumulation　layer　peeling　stage,　(2)　accumulation　layer　cracking　stage　and　(3)　overall　collapse　stage.　©　2024　Elsevier　B.V.
