PFC2D simulation research on vibrating compaction test of soil-aggregate mixture |
| |
Abstract: | In the paper the vibrating compaction process of soil-aggregate mixture of different ratio of soil and rock under the condition of certain graduation was simulated according to particle distinct element method based on particle motion pattern and density formation mechanism during vibrating compaction process of soil-aggregate mixture. At the same time Micro flow behaviors and structure properties of the particles was discussed. Some helpful conclusions were drawn. |
