It is thought that the loose slope itself evolves towards the critical state,and the evolution features present two kinds of different kinetics actions:for uniform-granule loose slope,its large scale avalanches obeying quasi-cycle distribution,for non-uniform-granule loose slope,its avalanches obeying power-law distribution,and arising self-organization criticality .

According to in-situ monitoring data, the displacement of rock slope varies with time, and the variation of air temperature is doubted to be one of the influencing factors.
