Abstract According to dynamic model test similarity relation this paper constructed a bedding layered slope model with the physical dimension of 3.0 m(L)×0.8 m(W)×1.6 m(H) is carried out a large-scale shaking table test. And the testing results show that at the slope surface amplification effect is nonlinear and sectional，while below the 1/3 and over the 2/3 of slope height the amplifications are obvious. At the vertical direction in the slope，acceleration amplified with the slope height nonlinearly，and acceleration amplification coefficient reached to peak value at slope shoulder. At the horizontal direction，acceleration amplification coefficient at slope surface is larger than that in the slope，and it shows tend-surface effect. The mechanism of blocking the river is that arthquake inducing→tensile crack and loosen appeared of rear top→shear extrusion damage of foot of slope→high speed sliding→blocking of the opposite bank-accumulation at base of slope→formation of barrier dam.

Key words： slope engineering bedding layered rock slope large-scale shaking table test acceleration response rules acceleration amplification effect mechanism of blocking river
