The study looked at how slope stability is affected by heavy rainfall and slope-top loading. They used a method called strength reduction with FEM and Midas-GTS to calculate slope stability. Results showed that adding slope-top loading decreased safety by 16-21%, while increased rainfall decreased safety by 10-19%. Heavy rainfall had a bigger impact on slope stability than slope-top loading. Overall, heavy rainfall is the main factor affecting slope safety, especially when combined with slope-top loading. It's important to focus on slope drainage to prevent landslides in the future.
