Influence of Particle Shape on the Macroscopic and Mesolevel Mechanical Properties of Slip Zone Soil Based on 3D Scanning and 3D DEM

The macroscopic and mesolevel mechanical mechanisms of slip zone soil are a crucial subject for the research landslide deformation evolution slope control, but effects shape psephicity coarse particles in on properties still need to be explored. Discrete element method (DEM) can effectively monitor track parameters geotechnical materials, such as displacement vector field, contact force chain, particle coordination number. rock blocks medium-sized shear test undergo sophisticated process by 3D scanning technology, database is established accurately modeled combining DEM simulate indoor numerical investigation line with conditions. simulation results demonstrate that significantly affect dilatancy specimens. In addition, models featured poorer more irregular display evident dilatancy, larger numbers, well better density inside model. Some references study provided.
