从泥石流体应力应变自组织临界特性的观点出发,探索了在暴雨激发下,斜坡松散碎屑土触变液化系统内部不同因子间的相互非线性作用,使得斜坡碎屑土自然地朝临界极限应力状态发展,最终暴发坡面泥石流.并根据沟道中黏性泥石流阵性流输移系统的自组织临界特性,以及泥石流规模与频率间的幂律关系的观测分析,阐述了泥石流体自组织结构的相似性. From the viewpoint of the self-organized criticality of stress and strain of debris flow fluid, the interaction between different factors in thixotropic loose thixotropic liquefaction system is explored under the condition of rainstorm so that the slope detritus soil naturally moves towards the critical limit stress And finally the outflow of debris flows from the slope.According to the self-organized criticality of the viscous debris flow transport system in the channel and the observation and analysis of the power-law relationship between the scale and frequency of the debris flow, the paper describes the self-organized structure of debris flow Similarity.
