摘要: 岩石在断裂破坏过程中微缺陷的定量描述始终是CT图像分析的关键。结合分形理论较为详细地描述了微缺陷量化表达的全过程,同时也探讨了岩石在断裂破碎过程中分形维数的变化规律,为真正掌握岩石破坏机理奠定了基础。

Abstract: The quantitative characterization of the microdefects of rock fracture process has always been the key of CT image analysis. The whole process of the  quantified representation of microdefects is detailed in combination with fractal theory. The change law of the fractal dimension in rock fracture destruction process is also discussed, laying a foundation for a true understanding of rock destruction mechanism.

Key words: Rock CT image, Rock destruction mechanism, Fractal dimension
