| Summary: | The Bailongjiang River Basin is a high-incidence area of debris flow in my country. A large amount of solid and loose material accumulated in the valley under the excitation of heavy rainfall can easily form debris flow. The particle size distribution of loose solid matter affects its mechanical properties, which in turn has a great influence on the initiation of debris flow. After heavy rainfall, large-scale shear damage in the loose accumulation body is transformed into debris flow. Taking 16 debris flow ditches that have recently experienced debris flow in the Bailong River Basin as the research object, the representative accumulation samples were taken, and their basic physical and mechanical parameters were tested through indoor geotechnical experiments. The particles of the samples are analyzed by sieving and laser particle size analyzer, and the characteristics, properties, particle size fractal structure and particle gradation relationship of debris flow deposits are analyzed by statistical graphic |
