WebMay 13, 2024 · Based on the coupling of surface runoff and interstitial flow, we propose a modified failure mode for shallow soil slopes. In this mode, the safety factor of the shallow soil slope is derived, while the shear force acting on the slope from surface runoff is considered, as well as the resistance from the upper and lower edges of the sliding body.
