Bedding rock slopes are widely distributed in southwestern China, where earthquake-induced landslides frequently occur under the control of weak interlayers. To investigate the seismic response mechanisms influenced by slope geometry and weak interlayer parameters, a simplified numerical model was developed based on a typical slope located in Ludian, Yunnan. Parametric analyses were conducted on slope geometry, mechanical properties of rock strata, and characteristics of weak interlayers, including position, thickness, inclination angle, and shear modulus. The results indicate that topographic features significantly affect seismic response, manifesting as distinct elevation amplification and energy concentration on steep slopes. Rock bedding planes exert regulatory effects on seismic amplification, while weak interlayers substantially alter the slope's dynamic behavior. Among the interlayer parameters, shear modulus has the greatest impact, followed by position, thickness, and inclination angle. Notably, the interlayer inclination shows a critical transition zone between energy dissipation and amplification. These findings provide theoretical support for seismic analysis and engineering reinforcement of stratified rock slopes in seismically active regions.
