Abstract: In the paper the vibrating compaction process of soil-aggregate mixture ofdiferent ratio of soil and rock underthe condidon ofce,ro tain graduation was simulated according to parucle distinct element method based on particle motion pattern and density formation mechanism during brating compaction process of soil-aggregate mixture．At the same time Micro flow behaviors and structure properties of the particles was discussed．Some help conclusions were drawn．

Key words: soil-aggregate mixture, 2℃, ratio of soil and rock, structure and property

摘要： 笔者在文中针对土石混合料振动击实过程中颗粒运动规律和密度形成机理问题，引入PF。颗粒离散元方 法，模拟了一定级配条件下不同土石比的土石混合料的振动击实过程，探讨土石混合料振动击实中颗粒的微观运 动和结构性能，得到了一些比较理想的结论
