摘要：

PFC2D discrete element modeling program is applied to simulate the vibrating compaction process of soil and rock aggregate mixtures. Different gradations of soil and rock aggregate mixtures are considered; and the porosity and dry density values of the soil and rock aggregate mixtures are tracked during the simulation. The compaction curve is consistent to the physical test. The particle motion pattern and density formation mechanism are investigated during the vibrating compaction simulation. The particle flow behavior and the structural properties of the particles of different gradations are discussed.
