| 摘 要： | 应用分维理论对虎跳峡龙蟠右岸分布的土石混合体粒度分布的分维规律进行了研究分析,建立了平均粒径与相应的分维数之间的定量关系模型。通过研究表明,土石混合体具有良好的统计自相似性,由于其本身为级配不良土,在分维曲线上表现为双重分形分布,这种特殊的分维分布与土石混合体的成因及形成过程有关。

| Abstract: | The fractal characteristics of particle size distribution of soil-rock mixtures in the right bank of Long-pan in Tiger-Leaping Gorge area are studied by using fractal geometry theory.The quantitative equations reflecting the relationship between particle size average and fractal dimensions are established.It is found that the statistical self-similarity of particle size distribution exists in the soil-rock mixtures.For the soil-rock mixtures is poorly graded,the fractal curve shows special double fractal dimensions,which has relations with the origin and formation of the soil-rock mixtures. |
