This study investigates the dynamic response characteristics of gravel soil slopes under strong seismic loads through centrifuge tests. By simulating different earthquake magnitudes and slope angles, we analyzed deformation, acceleration, and stress variations in gravel soil under intense seismic conditions. Experimental results demonstrate a significant correlation between vibration frequency, amplitude, and slope stability. As seismic intensity increases, slope deformation becomes more pronounced, with failure modes closely related to soil particle size and density. These findings provide theoretical foundations for optimizing seismic-resistant design of gravel soil slopes and offer experimental data support for post-disaster reconstruction efforts.
