摘要
介绍了一种利用图象处理技术结合地理信息系统(GIS)软件的数据提取技术,从而计算土体中颗粒形态分形维数的方法,讨论了在图象处理过程中阙值的确定方法。通过对郧县膨胀土土样微结构图象分析,论证了黏性土微观结构的分形特征,并分析了分形维数与土体微观结构类型间的关系。
This paper presents a method to determine a fractal dimension associated with microstructure of clayey soil by image-processing techniques and Geographical Information System (GIS) software. And the method of determining threshold in image-processing is discussed. Through analysis of SEM of clayey soil of Yun County of China, a conclusion is drawn that the microstructure of clayey soil is fractal, and the relationship between the fractal dimension and the microstructure of clay soil is invertigated.
