【 摘 要 】

The shock wave characteristics of underwater moving explosive were studied with AUTODYN. The results show that the explosive velocity has different influences upon the peak overpressure in different directions and different distances. By converting the kinetic energy of the explosive into an equivalent static dose, the Cole empirical formula can be used to calculate the underwater peak overpressure in the direction of the explosive motion.
