Abstract

In this paper, fractal structure of granulometric distribution of fluid and accumulation in debris flow are analysed based on fractal theory. The Fractal dimensions values of fluid and accumulation of debris flow are between 2 to 3, and its average values are about 2.71 and 2.65. Fractal feature of water system of debris flow gully and its variational situation of fractal dimensions in different observation scales are studied. The results show that fractal dimension can be taken as a parameter describing granulometric composition of debris flow and water system of debris flow gully, reflecting the evolutional property of debris flow activity. The significance of fractal dimension is discussed.
