摘要
介绍了分形维数的基本理论，并基于此理论对某边坡的裂缝形状进行了分析，并利用Matlab的图像处理和数值计算功能，得出了不同时刻裂缝位移的分形维数。通过比较和分析发现，该边坡在不同的安全状态下，边坡裂缝分形维数的变化有一定的规律。因此可以通过对该边坡位移分形维数变化规律的研究，在对其他边坡进行安全综合评价时，利用该规律给其他边坡的安全状态的判定提供一定的参考。
The basic theory of fractal dimension is decribed, and then the cracking shape of a slope is analyzed based on this theory; in which the fractal dimensions of the cracking displacement at different time are obtained with the functions of image processing and numerical calculation of Matlab. Through the relevant comparison and analysis, it shows that the change of the fractal dimension for the cracking of the slope has a certain law under different safety status. Therefore, through the study on the change law, a certain reference can be provided by it for the judgments made on the safety status of the other slopes during their comprehensive safety appraises.
