摘要The density of debris flow samples after settling in laboratory (the deposit density) is a kind of limiting density of debris flow, which depends only on the solid component in debris flow including particle composition, size distribution and arrangement. It does not change with the amount of water, This property of deposit density characteristics the type of debris flow. The tendency as well as the reason for change between deposit density and particle component is analysed in the paper. Samples from moving flow in the Jiangjia Ravine near Dongchuan City were obtained and the natural density and deposit density measured. The ratio of natural density to deposit density as a function of debris flow structure, the type and the properties of debris flow ere further researched.
