| 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. |
