STUDY ON THE SIMULATION OF THE FRACTAL DISTRIBUTION JOINTS
分形分布节理的模拟研究

Based on the discussion about the simulating method of fractal ditribution joints by computer and the analysis of effect factors on the fractal, a demostration of the following points is given. Fractal distribution joints can be well simulated by a descending cascade prosess, and their fractal dimension almost is not affected by the length distribution dimension or the length ratio of the joints. But influences of the effective scale range of the fractal on its dimension deserves an extra attention. The main factor affecting the fractal dimension is the cluster dimension of the joint midpoints, rather than their mean length and set number, which only affect the position of the scale range.
