【摘要】 对粒径不同的集料进行压碎筛分试验,发现尽管原始颗粒的粒径有较大的差异,但其破碎生成的细颗粒的级配却有非常相似的特点;得出集料的破碎是一个遵守严格规律的过程,而由于集料破碎所具有的非确定性、模糊性、非线性正是分形的特点,用分形理论可以解释并得出这一规律,以指导级配设计。更多还原

【Abstract】 A deep analysis and evaluation has been done on investigation data of the aggregate crushing test,although the original sizes of aggregate are different,the gradation which was produced by original aggregate are similar,therefore useful conclusion of aggregate crush comply with law is gotten.Because of the uncertainty, fuzziness and nonlinear of aggregate crush are very accord with fractal theory,it can explain and get the rule of aggregate crush by fractal theory.更多还原
