A New Method to Estimate Routine Based on the Motion Modes of Rockfall

Article Preview

Abstract:

This article divides the motion route into four phases: free fall, initial collision, in-flight and subsequent collision. There could be bounce, slippage or rolling movement in the phases of initial collision and subsequent impact. Based on the theory of movement mechanics, the certain methods on the motion direction, velocity and distance of each movement mode is established and the effected discrimination standard to distinguish the motion phases and modes is put forward.
