Numerical Simulation and Analysis of Motion Process of Incompact Soil along Slope
Simulating motion process of incompact soil. Monitoring evolution process of average contact force and unbalance force between particles during moving; Recording microscopic parameters and its changing processes, incliding spatial locations, translational rate and rotation rate of specific particle during the moving. Simulation results properly reproduced the whole process of it along slope, which include the starting, moving, piling up. Simulation results indicate that: Process of its motion manifest the macro space position changes, as well as, are the change process about contact stress, unbalance force within the inter particle and single particle movement mechanics etc. Size of average contact force reflects close degree between particles, fluctuation extent of microscopic parameter and levels of interaction between particles. Microscopic parameters of movement process can be used in the theoretic modeling analysis of complex movement of the incompact soil.
