| 摘 要： | 根据分形理论,对潘集矿区底含沉积物的68个样品进行了颗粒分形计算。结果表明,所有样品皆具有良好的分形特征,分维值(D)在2.52~2.80之间,平均值为2.69;分维值与表征沉积物水理性质的指标黏土质量分数、不均匀系数以及渗透系数有较密切的关系,可以作为沉积物粒度分析的参数之一。

| Abstract: | Sixty-eight sediment samples are calculated based on the fractal theory.The result shows that all the samples have the fractal feature,and the values of their fractal dimensions(D)are between 2.52 and 2.80,and the average value is 2.69.The fractal dimension D has close relation to some parameters which can illustrate sediment's hydrophysical features,such as the clay content,the coefficient of uniformity and the permeability coefficient.Thus D can be regarded as a useful parameter in grain-size analysis. |
