Based on theoretical research, waveform curve of shock wave and the pressure data of underwater group of satchel charges were measured by doing the monitoring test in the waterway dredging project of the second-phase construction in Gulei Xiamen. Characteristics and the law of its propagation of shock wave in water produced by the explosion were analyzed, the conclusion which the single dosage is 110 ~ 500kg while the total dosage is 730 ~ 4710kg and the blasting distance is from 74.5 to 220m was given. Semi-theory-semi-experienced formula of the shock wave on this condition was verified. Much valuable experience has been accumulated for the further research.
