土石混合料粒度特征及其分维研究

阐述土石混合料的粒度分布具有分形特征，分形理论可用来描述土石混合料的粒度分布。采用质量来确定DF较为方便，且能获得令人满意的效果，同时，颗粒分析试验的数据可直接用来计算DF。研究结果表明，分维值越高，细粒物质的相对含量就高；分维数越低，粗粒料的含量就越高。将啡作为土石混合料的分类指标，具有一定的可能性。

Research on Grain Size Features and Fractal Dimensions of Soil-stone Mixed Materials

This paper expatiates that the grain size distribution of soil-stone mixed materials has the fractal features, and the fractal theory can be used to describe the grain size distribution of soil-stone materials. It is convenient to determine DF _by means of mass and the satisfactory result can be obtained, in the meantime the data from the grain size analysis test can be used directly to calculate DF.. The result of research shows that the higher the fractal dimension, the higher the relative content of fine-grained materials ; and the lower the fractal dimension, the higher the content of coarse-grained materials. Therefore, there is a certain possibility to use Dr as the classification index for soil-stone mixed materials
