<p>Rock slopes with cracks may remain stable under static conditions, but large-scale landslides may occur when subjected to seismic excitations. However, the presence of cracks has been long overlooked in existing studies on the dynamic stability of rock slopes. Attempts are successfully made in the current work to conduct comparative shaking table tests on bedding rock slopes with and without cracks, where the dynamic responses and failure modes of both types of slopes are systematically investigated. The results indicate that the presence of cracks significantly influences the propagation and response of seismic waves in slopes. When the input seismic amplitude exceeds 0.4&#xa0;g, both types of slopes exhibit nonlinear dynamic response characteristics. The evolution process of slope surface displacement can be categorized into three stages: elastic deformation stage, plastic deformation stage, and failure stage. The damping ratio and natural frequency of both model slopes respectively show gradually increasing and decreasing trends, thereby the relationship between seismic input motion and damage coefficient has been established. The presence of cracks obviously alters the failure mode of the model slope and significantly increases the landslide volume. The bedding rock slope without cracks exhibits a single-stage sliding trend, while the one with cracks presents a multi-stage sliding trend. The findings of this research might facilitate the stability assessment and seismic design of bedding rock slopes.&#xa0;</p>
