Abstract For knowing the degradation processes of slate on suffer layer of mudflow channel in Zhouqu and Wudu located at the middle and lower reaches of the Bailong valley，we studied the physical degradation of slate using field photograph，varying quality variations，elastic velocity，stress-strain curves，and uniaxial compressive strength. These tests were carried out following varying numbers of cycles of thaw-freeze，wet-dry weathering. By applying correlation regression and fitting analyses，we real the degradation rules regarding the correlative index of slate by contrasting analyses following thaw-freeze，wet-dry weathering processes. The degradation of response of the functions to the degradation of slate is used to elucidate the degradation behavior and mechanisms of slate in the different functions and manifest that the major influent factor is the function of wet-dry. Our results provide a reference for evaluating slope stability，and predicting the potential for debris flow disasters in the study region.
