Other AbstractBased on the particle distribution of 75 gravel soil samples from 19 debris flow valleys, the fractal theory
is applied to study the characteristics of particle composition of gravel soil , the relationship between the characteristics
of fractal dimension and particle composition is discussed later. The results show that: 1. the gravel soil possesses
the characteristic of fractal,a nd mainly in one dimension fractal; 2. particles with one dimension fractal is fine
graded; particles with two dimension fractal is weak graded,and it emerges when there exists a particle abrupt; 3. the
average particle size fractal is between 2. 45 and 2. 78 in the 19 debris flow valleys,and it goes up with the increasing
of clay content. The relationship between particle size fractal in one dimension and clay content can be expressed
by: Da = 0. 108ln( pc) + 2. 511. At last, the significance of researching on the fractal characteristics of
gravel soil in original area of debris flow valleys is discussed.
