Abstract: Aiming at assessing the safety of an ancient landslide site, numerical stability analyses are conducted considering changes in hydraulic conditions. Through finite element simulation, two primary factors influencing slope failure, i.e., groundwater level rise and rainfall, are investigated. The results indicate that when the groundwater level surpasses the sliding zone, the stability of the ancient landslide diminishes, leading to a change in the sliding mode. The sliding mode is affected by both the water level and the dry density of soil in the sliding zone. However, landslide stability does not exhibit sensitivity to sudden heavy rainfall.
