Evaluating the dynamic response and failure process of a rock slope under pulse-like ground motions
Geomatics, Natural Hazards & Risk, 2023 Earthquake-induced landslides represent a significant proportion of seismic hazards in mountainous areas. Numerous slope stability analysis methods exist; however, only a few consider the interactions between pulselike seismic waves and landslides.
