%X In this paper, we designed and conducted a set of shaking table model tests of soil slope according to the topographic and geomorphologic conditions of the slope. Based on the results, we examined the influence of the topographic and geomorphologic conditions on the dynamic response of the soil slope and studied the reaction mechanism of slope under earthquakes. Results demonstrated that the dynamic response of soil slope was  closely related to the elevation of the slope. The amplification coefficient of peak ground acceleration (PGA) along the slope surface and in the vertical direction of the slope increased with the elevation increasing, and the amplification effect of soil inside the slope to earthquake waves was more significant than that of slope surface in the horizontal direction. The topographic and geomorphologic conditions of the soil slope had great influence on the amplification effect of earthquake waves. Generally, if the slope is steeper and more complex in shape, the amplification coefficient of PGA and the deformation of the slope will be greater.
