Abstract：In order to analyze the deformation and failure mechanism of the loess slope in the northern slope of a certain mine in Shanxi and the changes in slope stability after continuous rainfall,a simplified engineering geological model and calculation model of the BB23-1 section in the northern slope were established based on existing geological data and actual on-site operations.Through research methods and means such as finite element modeling,the deformation and failure mode of the loess slope was determined based on the changes in the loess slope within 9 days of rainfall The variation of stability coefficient indicates that with the continuous increase of rainfall,the mechanical shear strength of the loess layer decreases,and the slope is in a limit equilibrium state on the 9th day of rainfall.
