The different boundary conditions are discussed, which include the fully restrained boundary, half-restrained boundary, and free boundary on the safety factor of slope. The effects of geometric and strength parameters on the safety factor of slope are then examined. Discrepancies between the slip surface shape and the escaping points are also presented to assess slope stability.
