Abstract
Using Videolab Image Processing System, the microstructural changes of clayey soil in the process of compaction are quantitatively assessed These quantitative indexes include void ratio, average size, average form factor, the distribution of orientation angles, main orientation angle and anistropy etc A new quantitative index probability entropy is proposed for assessing the ordering extent of microstructural units Finally, the mechanisms of compacting properties of clayey soil are analysed according to the quantitative results
