Abstract Rainfall-induced landslides are the most frequent and catastrophic geological disasters，while the accurately early warning of precipitate landslides in response to intense rainfall is still challenging. Understanding the rainfall-induced mechanism of landslides is the prerequisite for the early warning. In the study，a typical post-earthquake landslide in Dujiangyan County was selected as a real-time monitoring site，and the stability and failure mechanism of the slope were investigated in a long period by combining the real-time monitoring data of five hydrological years and hydro-mechanical coupling theory. A landslide warning model with multi-parameter thresholds including rainfall intensity-probability threshold(I-P)，saturation，matric suction，inclination and slope stability，was proposed based on the unsaturated slope stability calculation and the long-term monitoring data analysis. The proposed method was successfully implemented in early warning at Yindongzi gulley in Aug. 2017 and Jun. 2018 and proved reliable and practicable. The research provides a reference for early warning of rainfall-induced landslides.
