摘要

从损伤理论出发，构筑一套细观量化试验方法，解决从试验制样、试验设备到试验程序等相关问题。采用扫描电镜对四川锦屏大理岩进行了观测，得到了大量岩石细观结构图片。利用数字图像处理技术对图片进行处理，并编制相关程序实现图像二值化，然后从图像中提取了微裂隙的长度、方位角、宽度、面积和周长等微裂隙细观信息。最后，利用统计学理论对获取到的微裂隙细观信息进行了统计分析，得到各参数的统计规律，为研究岩石的宏观破坏提供了依据。

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.
