Study On The Dynamic Impact Of Dry Debris Flow On Resistive Structure

This paper is based on the model of dry debris flow and calculation of PFC2 D particle flow to analyze the dynamic impact of dry debris flow on resistive structure. Through the study found that dry debris flow motion contains both friction mechanism and collision mechanism, which the mutual transformation of debris flow have a significant impact under different volume, slope with the change of the thickness of fluid, impact Angle, analyzed the relationship between debris flow impact and influence factors; The impact force on the resistive structure of different height undertakes non-linear characteristics, which contributes to soil arch effect. It is proved to be existed among particles 、bottom plates and resistive structures in the motion process by calculation of PFC2 D particle flow. In the end, a further discuss and analysis about the impact of dry debris flow is lunched to analyze how the impact force changes with factors such as different structure forms 、particle shapes and plate coefficients.
