单轴压缩下大理岩细观裂纹扩展试验研究

摘要

This paper made real-time dynamic monitoring system and digital image processing technology using Scanning Electron Microscopy (SEM) with loading device, made quantitatively analysis on micro cracks initiation, propagation process in uniaxial compression of marble specimens, obtained the micro cracks propagation law, had certain theoretical meaning for rock mechanics research.%利用带有加载装置的扫描电镜（SEM）实时动态观测系统和数字图像处理技术,对大理岩试件在受单轴压缩时所产生的微裂纹的萌生、扩展过程进行了定量分析,得到微裂纹扩展的规律,对岩石力学研究有一定的理论意义。
