摘　　要：用数值方法计算了开阔空间中布置在炸药周围的水对爆炸冲击波的削波作用。计算结果与实验测量数据进行了比较。计算表明 ,在炸药周围布置 1～ 5倍于炸药质量的水可以把爆炸冲击波峰值压力减小17%～ 46 %。Water can absorb a lot of explosion energy in free fields and delay shock wave by means of obtaining kinetic energy. Water effects on shock wave propagation in a free-field environment were studied numerically. Numerical results are in good agreement with experimental measurements. The results show that peak overpressure is reduced by 17%-46% when explosives are surrounded by water with the amount of 1-5 times of explosive mass. The role of the air gap between explosive and water was studied.
