摘要：In this paper, simulated rainfall infiltration phenomenon on the loess slope under rainfall condition based on seep/w model and studied the mechanism of rainfall on loess slope erosion from microscopic perspective by analyzing the distribution of pore water pressure in different monitoring locations at different times during rainfall. The results showed that under the condition of rainfall, the slope shoulder that is nearest to the slope top is always in high water pressure and is the first place where runoff erosion begins; and with the increase of the slope gradient, water pressure of each monitoring site gradually increased and the degree of erosion of slope surface erosion is more serious.
