Rainfall infiltration is a key factor to induce landslides, and it is important to study the rule of rainfall infiltration on slopes for the prediction and prevention of landslides. This paper combines the minimum potential energy method with the existing analytical solution of seepage field, and proposes a new method for unsaturated soil slopes under rainfall conditions. Specifically, the total potential energy function of the unsaturated soil slope is established by considering the real-time changes in system potential energy caused by rainfall infiltration. Additionally, the effects of rainfall infiltration on the shear strength of the soil, the self-weight of sliding mass and the seepage force are considered. The ratio of the slip resistance moment to the sliding moment is defined as the safety factor (SF) of the slope. The real-time evaluation of the stability of unsaturated soil slopes is realized during rainfall. The research results show that the results obtained by the proposed method are closer to the reference solutions. Meanwhile, the rules of rainfall intensity as well as slope angle on slope stability are conducted. Finally, the relationship between the sliding depth of failure surface and rainfall is also studied.
