Computer Processing Technical Analysis on Consolidation Microscopic Image of Soft Soil

摘要

By the environmental scanning electron microscope technology, the microstructure images of soft soil were collected. The computer program process the micro images, including preprocessing, binary threshold segmentation, cell and pore distribution data analysis. The microstructure type and deformation law of soft soil before and after consolidation is contrasted. Research shows that, after consolidation deformation, large particles of soil sample increase, and small particles decrease. The particle equivalent size decrease and average shape coefficient increase, with directionality reduce. The pores among particles turned to internal pore of aggregate. Through the process of soft soil consolidation microscopic image by computer program analysis, the essence factors and macro deformation mechanism is summarized to guide engineering practice.
