A field dynamic compaction test of filled ground is carried out in a construction site in northwestern suburb of Beijing. Under the conditions of different blow counts and compaction energies
the subsidence of ground changes by phases. At the same time
quantitative analyzing of structure images is carried out on the samples of different compaction phases. The correlativity between microstructural parameters and the change of subsidence of filled ground is found. The test results reveal the law of controlling structure as viewed from microcosmic study during dynamic compaction.
