Abstract

In order to learn the microstructure mechanics property of lime solidify soil, the digital image tracking technology has been introduced and used to track the soil particles, based on the micro-images captured by the long work distance telecentric microscope lens. On one hand, the sample of lime solidify soil is made into cylinder specimen. One of the half-parts is taken as the experimental specimen. Then, the region plane observed in the middle of soil specimen is compartmentalized nine small regions. One of the small regions is the tracking objective. When the objective is tracked successfully, the images of nine regions under the same loads are captured. On the other hand, using the transformed correlation formula, the tracking speed is improved. Moreover, According to the characteristic of soil under loads, the objective is successfully tracked by selecting the rectangle template and rectangle search region. Finally, using the image processing method, the evolution regulations of the porosity of soil sample under uniaxial stress are obtained. That is, the porosity is increased with the rising stress. In conclusion, the microstructure characteristic of lime solidify soil is agree with the macro property of lime solidify soil.
