Abstract：A large-scale shaking table model test of slope with the scale of 1∶10 was introduced. The model slope was built by soil with a height of 2.15 m，length of 3.5 m，thickness of 1.5 m，and a slope angle of 38°. A series of tests were performed with different input seismic wave kinds，amplitudes and frequencies. The dynamic characteristics and dynamic responses of slope under earthquake，as well as the influence of ground motion parameters were discussed. Results show that the natural frequencies of model slope decrease with the increasing vibration number，and the decrease range expands with the increasing earthquake amplitudes，while the damping ratios increase with their increasing. The slope has amplification effect to input seismic waves，and the effect become extremely prominent around the crest of the slope. The acceleration responses have obvious difference under different input seismic waves. The amplification effect of peak acceleration enhances evidently when the predominant excitation frequencies of input seismic waves approach to the natural frequencies of the model slope；and the amplification coefficients of the peak acceleration along slope surface decrease with the increasing earthquake amplitudes. The soil in slope has amplification effect to input seismic waves at high frequency and filtering effect at low frequency；and the filtering effect becomes more prominent with the increase of earthquake amplitudes. The results are helpful to reveal the mechanism of slope instability under earthquake，and provide valuable references for aseismic design of slope engineering.
