摘　　要：基于离散元理论方法,以AC-13、SMA-13两种混合料作为研究对象,介绍生成颗粒的方法,对比两种混合料颗粒生成情况与现实是否相符,结果表明:建模得到的两种混合料是悬浮密实型和骨架密实型,与实际相符;以两种混合料的劈裂试验为基础分析两者的性质,验证离散元方法的可行性。we take AC - 13, SMA - 13 mixtures as the research object, and describe the method of generating particles which is based on the theory of discrete element method. We judge whether the result of generating two mixture particles is consistent with the reality, results show that ： two kinds of mixtures are suspended dense type and skeleton dense type, and agree with the actual situation ; anal-ysis properties of two kinds mixed material based on splitting test to verify the the feasibility of discrete element method, and a new train of thought is proposed for the research of the mixture properties in the future.
