Using large 1:30-scale shaking table model tests, we studied the dynamic response characteristics of acceleration of a high steep anti-dip stratified rock slope containing six siltized intercalations with a composite retaining structure, by inputting EL Centro and Wenchuan seismic waves in the X-and Z-directions, respectively. Test results show that:(1) The acceleration amplification coefficient grew nonlinearly with increasing slope height in both the X-and Z-directions, and the values of the former were greater than the latter. (2) The acceleration magnification effect at the slope surface is significantly affected by the water content variations of the siltized intercalation. The X-direction amplification on the water-soaked soft interlayer decreased in comparison with that of the initial conditions, however, the opposite was true in the Z-direction. (3) By the action of the retaining structures, the more restricted the magnification intensity of the slope free face, the more the amplification effect can be ignored where the altitude is less than 1/3 of the slope height. With respect to the elevation amplification effect of X-direction acceleration, a slope supported by hierarchical implementation is beneficial, but it is disadvantageous in the Z-direction. (4) The tilt-split model may be used as a failure model for a counter-tilt layer rock slope under earthquake conditions, which is controlled by the sliding of weak layers, particularly after rain. Damage is possible from the upper frame beam rotating around the slope crest, which can be pulled out using the pre-stressed anchor cable as a fulcrum.
