Firstly, three kinds of sand pile experiments which reflect the universalprocess of energy dissipation within the slope accumulation under the self-organizedaction are reviewed. They all show that self-organized criticality (SOC) is related togranular non-uniform. The experiment of Tokamak plasma system is introduced, whichshows some of SOC properties of Tokamak plasmas in Ohmic region or L-mode.Secondly, material tests in geotechnical engineering and numerical simulations ofmicro-structure of sand piles indicate that SOC is determined by the structuralcharacteristics. Finally, according to the principle of SOC, the behavior of slope disastersunder gravity and its forecast as well as the design of protection engineering arediscussed.
