基于图像处理技术的岩石裂纹演化及其多重分形的研究

Study on the Evolvement of Rock Crack and its Multi-fractals Based on Image Processing Techniques

用VC++开发岩石CT图像处理程序,提取岩石CT图像中的重要信息特征,并结合多重分形理论对岩石断裂破坏过程中的微缺陷进行了量化表达。结果表明,通过多重分形谱能够全面反映出岩石断裂破坏过程中微缺陷分布的完整信息,从而为进一步研究岩石断裂破坏奠定理论基础。

The images processing techniques of rock CT are developed with VC＋＋,obtaining the important information features from the images of rock CT.And the multi-fractals theory can quantify the microcosmic disfigurement in the process of rock breakage.It is concluded that all information of microcosmic disfigurement on rock breakage can be reflected by multi-fractals,and this provides a theoretical foundation for studying rock breakage.
