摘　　要：应用分形理论对大粒径碎石填料进行级配判定,分析了分形维数用于表示级配的方法,论证了分形维数和级配的关系,结合室内筛分试验得出填料的分形维数在合格范围以内,说明可用于级配优良性判定,且比应用不均匀系数和曲率系数更简单、快捷。The paper undertakes the grading judgment of the large particle size graded crushed rock by the fractal theory, analyzes the fractal di- mdnsion can be used as the method for displaying the grading, indicates the relationship between the fractal dimension and the grading, con- cludes the dimension must be within the qualified scope by combining with the indoor screening test, and illustrates it can be used in the grading better performance, and it is faster and simpler than the uneven coefficient and coefficient curvature.
