摘　　要：采用数值方法计算了封闭矩形空间中布置在炸药周围的水对爆炸冲击波的削波作用以及对于气室压力的削减作用。计算结果显示 ,在各种不同的载荷密度和水 /药质量比参数条件下 ,冲击波峰值压力和气室压力均得到明显的削减。还计算了一个具有开口的模型隧道中水的削波作用 。The mitigation effects of water on the detonations of explosive in a confined cube chamber are studied by using a numerical code. Significant mitigation effects on shock pressure and final static gas pressure have been obtained at various loading densities, as well as various water/explosive mass ratios. The water mitigation effects on shock pressure in a tunnel system with vent are further simulated. The numerical results are compared with the experimental data.
