Paper Title:
Dynamic Response of Horizontal Bedded Rocky Slopes under Earthquakes and Influence of Ground Motion Parameters
  Abstract

Two dynamic numerical simulation models of horizontal bedded rocky slopes were established with Finite Element Analysis (FEA) according to the archetype of rock slope in β€œ5.12” Wenchuan earthquake, and the simulation was validated with a shaking table model test. In the two models, one named A is the upper is hard and the bottom soft rock, and the other named B is the upper is soft rock while the bottom is hard. The result indicates that there exists amplification effect on elevation in both slopes under horizontal earthquake wave, the amplification factor of PGA in model A is larger than that in model B following the increase of the amplitude and the duration, and the slope displacement in model A is also larger than that of model B in the effect of the amplitude, frequency or duration. These show that model A is in disadvantageous compared to model B, and the stability destroy is produced easily in model A.
