Abstract: The test of quantification of rock mesostructure is designed based on damage mechanics and stereology theory. Some relating issues such as specimen preparation, experiment equipment and experiment routines are settled down. The scanning electron microscopy (SEM) is used to investigate Jinping marbles in Sichuan Province and thousands of mesostructural images are obtained. Then, SEM images are transferred into binary images by using digital image processing and compiled program; and the microcracks’ information such as length, angle, width, area, perimeter, etc. is obtained from the processed images by using functions. Finally, the information of rock mesostructure is statistically analyzed; and the statistical law of every parameter is obtained; it’s import to the research of macro-damage of rock.

Key words: marble, mesostructure, quantification, SEM, image processing
