Abstract
The present invention discloses a three-dimensional simulation and prediction method for the fragmented rock movement considering a dynamic fragmentation effect during the impact process. The method includes: establishing a rock mass structure model; acquiring dynamic parameters under a real environment, including a collision position vector {right arrow over (p)}=(P, P, P), a collision linear velocity {right arrow over (v)}=(V, V, V), and a collision angular velocity {right arrow over (ω)}=(ω, ω, ω); and simulating the collision, fragmentation, and movement processes of the rock mass. Based on the rock mass fragmentation model, whether the rock mass fragmentation occurs or not can be determined. Then, the trajectory of each fragmented block can be simulated using the energy distribution model and fragmented block trajectory model.
