The dynamic behaviour of clay with different initial density was researched by a single-stage light gas gun. Soil samples with four initial density (1.7, 1.8, 1.9 and 2.0 g/cm3) were investigated in this study, the water content, graininess and raw material of which were the same. Four electromagnetic particle velocity gauges were embedded directly into each sample, which was compressed by clay powder. And the motions of shock wave were detected by these gauges. Typical waveforms of the particle velocity and the Hugoniot data of the experiments were presented. The dynamic stress-strain relation could be determined by the Lagrangian analysis method which was utilized to the four particle velocity waveforms. The results show that, the initial density was possibly the most important factor to affect the dynamic behaviour of soft clay soil under intense dynamic load compared with the water content.
