Abstract: Effective depth of dynamic compaction was summarized, and the advantages of dynamic compaction technology of effective depth were analyzed elaborately. The formula determining the reinforcement depth was deduced by using dimensional analysis method. The influential factors of hammer weight, hammer area, dry density of filling materials and filling materials types were comprehensively investigated. The formula of effective depth was established based on the definition of the dimensions analysis. Based on experimental results of in-situ dynamic compaction, the technology was applied to highway embankment filled with soils and rocks. From the comparison between the theoretical calculations and the experimental results, it is found that the theoretical results using the developed formula are close to experimental results.
