This paper examines the landslide mechanism and deformation characteristics of the dynamically compacted slope highly filled with slag under rainfall infiltration. Based on the numerical model, displacement field, seepage pressure distribution, volume water content and safety factor are studied in detailed.The results indicate: 1) with continuous rainfall, the slope safety factor significantly reduces; 2) because of the lower permeability after dynamic compaction, seepage positive pressure focuses on the top of the slope within a certain depth and gradually increases and tends to stabilize under continuous rainfall; 3) vol.water content gradually increases to saturated status; and 4) shear failure occurs at the toe of slope under continuous rainfall, leading to collapse in the lower part of slope.
