分形理论在岩体质量评价中的应用研究

APPLICATION RESEARCH ON FRACTAL THEORY IN ROCKMASS QUALITY EVALUATION

简要地回顾了岩体质量评价体系，提出了一种利用分形分布与概率的联系来评价岩体质量的方法，并给出了相应的岩体质量评价的标准。研究表明，分维数 Ｄ能够弥补岩石质量指标 ＲＱＤ在评价岩体质量中的某些不足，可以作为评价岩体质量的一个定量指标。

By reviewing the system of rockmass quality evaluation, a new method is discussed to evaluate rockmass quality by using the relationship of fractal theory and probability theoiy. The evaluation criterion is also given. The research indicates that the fractal dimension D can avoid most of the shortcomings of Rock Quality Designation (RQD) in evaluating rock mass quality and it can be used as a quantitative criterion.
