The invention provides a dynamic monitoring and early warning method for a mine side slope containing a weak intercalated layer, and the method mainly comprises the following steps: determining a side slope early warning safety coefficient range (Fs-Fsd) according to the type and grade of the side slope and the working condition of the side slope; the method comprises the following steps: comprehensively obtaining mechanical parameters of a slope rock mass based on engineering geologic characteristics, a crustal stress field and slope excavation partitions of a slope by means of field testing, indoor testing and the like, establishing a slope model considering an excavation effect, and arranging monitoring points; determining a creep constitutive model and creep mechanical parameters through a weak intercalated layer creep test; a BP neural network and a numerical calculation method are adopted to determine safety coefficients corresponding to different rock mass physical and mechanical parameters, and the re
