| 摘 要： | 运用筛析法和比重计法，分析了宁夏膨胀土的颗粒分布，发现粒径介于0．002～0．1mm的粒度分布是分形的，分维介于2．46～2．67；运用上孔隙分布的分维确定水份特征曲线，得到了很好的结果。此外，还探讨了粒度分形分布的机制。

| Abstract: | Through granulometric analysis of Ningxia expansive soil, it is found that the grain-size distribution of expansive soil is fractal for diameter between 0. 002 to 0.1 mm, and its fractal dimension ranges from 2. 46 to 2. 67. Soil-water characteristic curve of soil is calculated by using the fractal dimension of pore distribution, and a satisfied result is obtained. The physical mechanism of fractal distribution of soil grainsize is studied in this paper. |
