A　shaking　table　model　test　was　conducted　to　study　the　dynamic　response　and　failure　mechanism　of　a　bedding　rock　slope　with　weak　rock　layer　based　on　the　＂Xiaguiwa＂　landslide　in　the　Jinsha　River　basin　of　Sichuan-Tibet.　The　influence　of　schist-like　weak　rock　layer　on　bedding　rock　slope　is　considered.　The　test　results　show　that　the　Peak　Ground　Acceleration　(PGA)　amplification　coefficient　varies　rhythmically　from　the　inside　to　the　surface　of　the　slope,　and　0.3　g　and　0.6　g　are　the　slope　appears　cracking　and　instability.　schist-like　weak　rock　layer　makes　the　seismic　wave　enhance　obviously,　but　in　the　slope　flexure　position,　the　seismic　wave　near　the　weak　rock　layer　is　slightly　weakened　instead,　and　the　maximum　displacement　often　occurs　above　the　weak　rock　layer.　the　＂bucking＂　occurs　at　1/4　of　the　slope　height,　and　the　fracture　degree　at　the　middle　and　lower　part　of　the　slope　is　greater　than　that　at　the　middle　and　upper　part,　and　the　slope　damage　surface　appears　to　be　＂concave　at　the　top　and　convex　at　the　bottom＂.　The　damage　process　of　the　model　slope　is　divided　into　four　stages.　The　model　test　results　reflect　the　influence　of　the　weak　rock　layer　on　the　seismic　dynamic　response　and　damage　process　of　the　bedding　rock　slope.
