摘要:
运用分形理论，提出泥石流粒度分维的概念及其计算方法。根究泥石流粒度分析结果，分别求解泥石流形成区原始土体粒度分维、流体粒度分维和堆积物粒度分维，并分析它们与泥石流体颗粒机械组成和流体性质方面的相互关系。泥石流粒度分维值为泥石流形成、运动和堆积特征以及流体性质提供了可供参考的指示意义。
Abstract:
According to fractal theory,the definition and calculating method of grain-size fractal dimension for debris flow were presented,and grain-size fractal dimensions of the original grains in the source area,grains in debris flow fluid and grains in accumulation area were respectively analyzed in detail.On the basis of fractal feature of the grains and the relationship between grain-size fractal dimension and grain composition,characteristics of debris flow,it is presents that the grain-size fractal dimension of debris flow can reflect the volume of the viscous grains,indicate the viscosity characteristics of debris flow,and the resistance property.The critical grain-size fractal dimension values might provide some useful indications for debris flow researches.
