摘要(Abstract):
通过对气泡帷幕衰减水中冲击波作用现象进行分析 ,基于实验结果 ,采用爆炸相似律理论 ,得到了适用于工程实际计算的经验表达式 ,并引入气泡帷幕的削波系数 ,对工程实际运用和计算装药水下爆炸对渔类的安全距离提供了理论依据和计算方法。
Through analyzing the phenomena of weakening the underwater shock wave by a bubble curtain, consulting the theory of blast resembling rule and considering the experiment data, an empiric formula is obtained for calculation of peak pressure of underwater shock wave in actual engineering A shock prevention ratio of bubble curtain and its expression are introduced, which give an efficient solution to the practical engineering and provide the theoretical base and a calculating method for determination of a safety distance for the effect of underwater explosion on fish
