Investigation of Rockfall Impact Against Gravel Cushion via a Discrete Element Approach
Abstract This study investigated the impact of rockfall impact against a granular cushion layer via 3-D discrete element method (DEM). In the numerical model, the rock boulder was modeled as a single sphere with an incident velocity, and the granular layer was modeled as an assembly of poly-dispersed spherical particles. The numerical model was calibrated and validated by comparing the numerical results with experimental data reported in the literature. It was further used to investigate the effect of rock boulder mass on the maximum impact force, impact duration and penetration depth. The obtained numerical results are in good agreement with available experimental observations.
