Research on Dimension Algorithms about Fractal of Micro-structure Curve of Rock by Using Box-Counting Dimension Method

This paper introduces the pavement of granite, basalt, limestone, etc coarse aggregate microstructure surface texture. Using MATLAB programming calculation, the contour line and the original data of fractal dimension, and with KOCH KOCH curve (etc) norm form for the calibration, graphics are calculated respectively the pebble granite limestone basalt data algorithm and graphics algorithm dimension of results. The results show that, when the box counting dimension method, using a graphic calculation method of stone material surface texture curve of the dimension of the calculation results of surface texture, more comparable nuances of recognition sensitivity, stronger, different types of stone obvious differences in dimension, results and actual situation trend to recommend in engineering practice using the algorithm.
