Velocity is an important parameter to reflect the dynamics of slope. A velocity sensors are arranged on the top of slope of the Xiaguiwa bedding rock model slope. A velocity sensor is arranged on the shaking table to record the real velocity state of the input seismic wave. The collected data are filteringed, noise reduction, screened and other processing steps to obtain the velocity data set of the bedding rock model slope; The peak values of the velocity data of the model slope under the same load condition can reflect the dynamic response law of the slope under such seismic action. The ratio of the peak velocity on the slope to the peak velocity on the table reflects the enhancement level of the velocity response of the slope top under seismic action.

A total of two types of seismic waves are used as input in the test, one type is sinel wave; the other type is natural wave, and the natural wave is adopted from Wenchuan Maoxian wave. The sine wave amplitude and frequency are unique, so it can be used to study the influence of ground motion parameters on the dynamic response of slopes. By comparing the dynamic response of slopes under the action of sine waves with different frequencies and amplitudes, the influence of the input seismic wave parameters on the dynamic response of rock slopes is investigated; the natural waves are selected from the bedrock seismic waves recorded at the Maoxian station. The seismic wave input is loaded in a step-by-step manner, firstly loading the sine wave with low amplitude, and then loading the Wenchuan Maoxian wave with 0.1g increase, and after each loading, white noise is carried out to analyze the natural characteristics of the slope. After each loading was completed, 10 minutes were spent to take pictures and observe the damage of the slope.
