土木工程人员经常用粗料颗粒分布分维、粗料轮廓分维这些结构指标作为土石混合体定量化研究的依据，用以解释土石混合体的力学特性，并以这些参数作为土石混合体工程分类的依据。目前技术人员以手工筛分实验来计算粒度分维数。展开对土石混合体微结构研究，劳动强度大，操作不便，极大地制约了对土石混合体微结构的研究。提出了利用数字图像处理技术来测量土石混合体分形维数的方法。实验验证结果表明，该方法减轻了工程技术人员手工检测的劳动强度，实用有效。

Some parameters including distribution fractal dimension of coarse grain and coarse grain boundary contour line are used as a new research method on microstructure of earth-rock aggregate by engineering technicians, which can explain the characteristics of mechanical behavior of earth-rock aggregate. The parameters of distribution fractal dimension can also be clas- sification basis for engineering of earth-rock aggregate. Now technicians can only calculate grain-size fractal dimension by sieve analysis in manual operation way to research on the microstructure of earth-rock aggregate, which restricts the technicians' fur- ther research for its great labor intensity and its inconvenient operation. In this paper the detection of distribution fractal dimension of earth-rock aggregate base on digital image process is put forward. This method is simple and practical. It can decrease labor intensity and enriched the research method of microstructure of earth-rock aggregate for technicians.
