Through dynamic compaction tests with tamping energies of 1500, 2000, and 2500 kN•m of an embankment section in the PingShan–ZanHuang Expressway, the compression deformation behavior of the tamping settlement, soil deformation around the tamping rammer, consolidation depth, and dynamic stress of dynamic compaction were comprehensively tested. Comparative analyses of field data under three different tamping energies suggested that the optimal tamping energy, number of strikes, and vertical effective tamping depth for this embankment are 2000 kN•m, six, and 5 m, respectively. The field test data proving that dynamic compaction has a significant effect on this embankment.
