摘要
以吉林省西部地区分散性土为研究对象,在颗粒分析试验的基础上,运用分形理论研究了分散性土的粒度成分分形特征。研究结果表明:土中砂粒含量越多,分维数越小,土的分散性越大;粉粒含量越多,分维数越大,分散性越大;粘粒含量越多,分维数越大,土的分散性越小。
Taking the dispersive soil in the west of Jilin Province as the research object,on the basis of the particle size analysis,the fractal features of granularity composition of the dispersive soil is studied using the fractal theory. The results show that the more content of the sand in soil,the smaller the fractal dimension,the greater the dispersion of soil; the more content of the silt in soil,the greater the fractal dimension,the greater the dispersion of soil; the more content of clay in soil,the greater the fractal dimension,the smaller the dispersion of soil.
