Abstract: Soil of debris flow has a broadly graded weight distribution, a great disparity in size, a high dispersion in fine components, which caused the effects of Particles Transport on Soil Pores Clogging(PTSPC)in the process of rainfall and seepage. Due to the interaction between soil and rainwater, small particles can be detached and transported, some of them may clog at pores, PTSPC decreased the permeability of soils in debris flow sources, PTSPC played an important role in the process of debris flow preparation and initiation. This research article summarized extensive literature of debris flow, and reviews relevant fine particles transport at home and abroad. Finally, several research directions were proposed based on the effects of PTSPC.The study provided new ideas for the mechanism of rainfall-induced debris flow, and a theoretical basis for disaster prevention and mitigation.
