AbstractThe paper presents experimental study of debris flows. The equilibrium concentration of solid particle in the flow is a function of the energy slope, density of solid particle and kinetic friction angle of particles. The kinetic friction angle is a function of internal friction angle, the concentration of solid particles and the maximum possible concentration. To determine the function between the kinetic friction angle and internal friction angle is the aim of this research. Flume experiments of equilibrium concentration about particles in water and slurry were conducted. The large density slurry made the coarse particles be able to move in small slope. The function between the kinetic friction angle and internal friction angle was found from these experiments. The coarse particles and fine particles are well mixed. D50 demarcation line was suggested in this paper to demarcate the coarse particle and fine particle of debris flows. The equilibrium concentration of debris flows was calculated by using Ds0 demarcation for the debris flows in field. The equilibrium concentration of debris flows calculated by the function between the kinetic friction angle and internal friction angle was close to the equilibrium concentration data of debris flows in field.
