摘　　要：本文研究了碎石多次压碎对压碎值指标的影响,并利用分形维数探讨了不同复压次数的碎石分形维数的变化规律,建立了分形维数与压碎值指标间的回归方程。结果表明,对于同一种类的碎石,随着压碎次数的增加,压碎值指标逐渐减小,分形维数也逐渐减小。对于同一母岩的碎石,其分形维数和压碎值指标有正相关性。In this paper,the influence of multiple crushing of crushed stone on the crushing value index is studied,and the change law of the fractal dimension of crushed stone with different crushing times is discussed by using fractal dimension,and the regression equation between fractal dimension and crushing value index is established.The results show that for the same kind of crushed stone,the index of crushed value decreases gradually with the increase of crushing times,and the fractal dimension also decreases gradually.For the crushed stone of the same parent rock,the fractal dimension has a positive correlation with the crushing value index.

关 键 词：碎石 压碎值指标 分形维数 压碎次数
