Abstract Many natural phenomena and natural disasters have close relation with granular materials avalanche, i.e. sand dune development and movement, debris flow, snowslide and earthquake. The sand-pile automaton model, the local limited model, the stochastic automaton model and the deterministic automaton model all has in some extent successfully simulated the avalanche phenomena of granular materials, but their results still have considerable difference with the fact due to limited conditions of experiment and simulation. It is necessary to conduct in-deep experimentation and theoretic analysis for find a universal theory explaining the avalanche phenomena of granular materials. Finally, some suggestions are put forward on how to solve sand piles avalanche problem in the future.
