Shake table testing was performed to investigate the dynamic stability of a mid-dip bedding rock slope under frequent earthquakes. Then, numerical modelling was established to further study the slope dynamic stability under purely microseisms and the influence of five factors, including seismic amplitude, slope height, slope angle, strata inclination and strata thickness, were considered. The experimental results show that the natural frequency of the slope decreases and damping ratio increases as the earthquake loading times increase. The dynamic strength reduction method is adopted for the stability evaluation of the bedding rock slope in numerical simulation, and the slope stability decreases with the increase of seismic amplitude, increase of slope height, reduction of strata thickness and increase of slope angle. The failure mode of a mid-dip bedding rock slope in the shaking table test is integral slipping along the bedding surface with dipping tensile cracks at the slope rear edge going through the bedding surfaces. In the numerical simulation, the long-term stability of a mid-dip bedding slope is worst under frequent microseisms and the slope is at risk of integral sliding instability, whereas the slope rock mass is more broken than shown in the shaking table test. The research results are of practical significance to better understand the formation mechanism of reservoir landslides and prevent future landslide disasters.

进行了振动台试验，以研究频​​繁地震作用下中倾层顺层岩石边坡的动力稳定性。然后，建立了数值模型以进一步研究纯微地震作用下的边坡动力稳定性，并考虑了地震振幅，边坡高度，边坡角度，地层倾角和地层厚度等五个因素的影响。实验结果表明，随着地震荷载时间的增加，边坡的固有频率减小，阻尼比增大。数值模拟采用动态强度折减法进行层理岩边坡的稳定性评价，边坡稳定性随着地震幅值的增加，边坡高度的增加，地层厚度的减小和边坡角的增加而减小。在振动台试验中，中倾角顺层岩石边坡的破坏模式是沿着顺层表面整体滑动，在倾斜的后缘穿过顺层表面时出现拉伸裂纹。在数值模拟中，在频繁的微地震作用下，中倾层顺层斜坡的长期稳定性最差，并且该斜坡具有整体滑动失稳的风险，而斜坡岩体比振动台试验更易碎裂。研究结果对于更好地理解水库滑坡的形成机理，防止今后发生滑坡灾害具有现实意义。在频繁的微地震作用下，中倾层顺层斜坡的长期稳定性最差，并且该斜坡具有整体滑动失稳的风险，而斜坡岩体比振动台试验更易碎裂。研究结果对于更好地理解水库滑坡的形成机理，防止今后发生滑坡灾害具有现实意义。在频繁的微地震作用下，中倾层顺层斜坡的长期稳定性最差，并且该斜坡具有整体滑动失稳的风险，而斜坡岩体比振动台试验更易碎裂。研究结果对于更好地理解水库滑坡的形成机理，防止今后发生滑坡灾害具有现实意义。
