Pseudo-static stability analysis is a widely used approach for assessing the seismic stability of slopes. It is a simple and efficient method that involves applying a static force to a designated facility to simulate acceleration in a model. When a structure is subjected to ground motions, the effect of shaking on the structure is equivalent to the force calculated by the seismic coefficient (kh). In this study, we investigated the stability of a laterally confined dip slope using a dynamic centrifugal model and the pseudo-static stability analysis. The experiment was conducted to examine the effects of various factors on the stability of the slope, including soil parameters, slope angle, and confining pressure. The results showed that the dip slope was highly susceptible to seismic loading and the pseudo-static stability analysis provided a reasonable prediction of slope stability. The findings offered valuable insights into the behavior of laterally confined dip slopes under seismic loading. The results can be used to inform slope design and guide engineering practices in areas prone to seismic activity. The use of dynamic centrifugal models in conjunction with pseudo-static stability analysis can improve our understanding of the behavior of laterally confined dip slope under seismic loading and enhance our ability to predict and mitigate the risks associated with seismic events.
