摘要
Fracturing and fragmentation processes occur on all scales and, hence, may be described in terms of fractals. We examined the fractal dimensions of discontinuity spacing measurements in a fractured rock mass and observed a relation between the fractal dimension and the quality of the rock mass in terms of RQD. RQD tends to increase with a decrease in fractal dimension for a given scanline length. Thus a relatively more-competent fractured rock mass will tend to have a lower fractal dimension and vice versa.
