钙质结核土细观结构定量分析研究
Quantitative analysis of cohesive soil microstructure
【摘要】 钙质结核土的结构特征对于其宏观力学性质和工程特性具有重要的影响。利用空间统计分析和分形维数计算方法,对钙质结核土的细观结构进行了定量分析,提取并计算了其颗粒形态、定向性等分形维数。结果表明,钙质结核的分布具有良好的分形特征和统计自相关性特点。
【Abstract】 The structure of cohesive soil containing calcareous nodules is essential to the study of macroscopic physical and mechanical properties and engineering properties.The paper presented a method to determine fractal characteristic of the micro-structure of cohesive soil containing calcareous nodules by GIS.The fractal characteristic was extracted,which showed that the distribution of calcareous nodules have good fractal characteristics and statistical autocorrelation.
