Through laboratory test, the course of drainage consolidation is simulated. It is aimed that the laws of particle migration can be resolved with the proposed approach. The test results confirm that the consolidation conditions affect the fine particle migration phenomenon. At the gravitational compaction consolidation stage, the fine particles are influenced by boundary conditions and seepage paths. The data analysis results show that the indicator can effectively reflect the degree of consolidation. With the continuing process of consolidation drainage, the “aggregate clay ratio” is increasing gradually. It reflects indirectly the strength of high clay dredger fill. In the consolidation process, “aggregate clay ratio” is increased as the drainage velocity is changed lower.
