Effect of Particle Form and Surface Friction on Macroscopic Shear Flow Friction in Particle Flow System

The damage caused by landslide disasters is very significant. Among them, landslides after forest fires have been widely concerned scholars in recent years due to their particular physical and chemical properties. This large-scale shear flow of particulate matter has similarities fluid systems. However, the discontinuity particle system, its process significant random characteristics. To investigate properties systems, this study conducted a series ring tests on four effects shape, normal stress, velocity systems’ rheological features were investigated using experimental data. form an important effect macroscopic system. In spherical friction fluctuation determined surface system’s stress. minor characteristic. Three elements simultaneously influence breccia system: friction, system velocity. origins frictional fluctuations systems with various shapes are fundamentally distinct. contributes better understanding causes fluctuations, establishes theoretical foundation for future development disaster prevention technology.
