排土场粒度分布与干涉区的分形特征研究
Study on the Particle Size Distribution of Waste Pile and the Fractal Characteristics of Interference Area
摘要
Abstract
By means of fractal statistical techniques , the dump material distribution was analyzed , and the interference effect among the material piles was also studied .The results show that the par-ticle size distribution of the dump has good fractal structure .From the bottom to the top , the fractal dimension gradually increases with finer rock grain size .The alternating phenomena of coarse grain and fine grain occur in horizontal direction .Besides, it has the characteristics of lower content of coarse grain and higher content of fine grain from outside to inside .Influenced by the interference effect, the interference area presents double fractal features , and the long axis direction of the rock is close to the low angle direction .This study provides a theoretical basis for studying the disasters of dump deformation, destroy, landslide, debris flow, rolling stone, etc.关键词
