Abstract Two bedding rock slopes with siltized intercalation were made and tested with large scale shaking table in this paper. The results show that with increase of inputted seismic wave predominant frequency，the amplification effect of slope face increase；when the inputted seismic wave amplitude is less than 0.3 g，the amplification coefficients of slope face increase with inputted amplitude increase，on the contrary，the amplification coefficient decrease；in horizontal，after the siltized intercalation was waterlogged，the amplification coefficients in slope foot is larger than that before waterlogged，the amplification coefficients in the upper part is less than that before waterlogged；in vertical，after the siltized intercalation was waterlogged，the amplification coefficient of slope face is less than that before waterlogged；the amplification coefficient of slope face is larger than that of slope body before the siltized intercalation was waterlogged，however，the amplification coefficients of lower slope body is larger than that of slope face after waterlogged，while the amplification coefficients of upper slope body is less than that of slope face；analyzing the process of failure of slope，it is found that the failure mode of bedding rock slopes with siltized intercalation is tension fracture-slippage-avalanche.
