Model Test Study on Impact of Landslide Debris Flow on Retaining Pile
[Purposes]Study the movement and impact process of landslide-debris flow on real three-dimensional terrain and its accumulation morphology.[Methods]Use PFC simulation to reproduce the model test to analyze the influencing factors of debris flow impact force.[Findings]Higher retaining piles can more effectively slow down the impact force and reduce the migration distance and accumulation length of the debris flow;when the particle size or volume increases,the impact force caused by the de-bris flow will increase;in the section where the retaining piles are located,the particle impact force is roughly normally distributed,with the middle pile receiving the greatest impact force,and the impact force gradually decreasing toward both sides.[Conclusions]The impact force of debris flow is studied through numerical simulation,which provides a reference for subsequent prevention and control.
