摘　　要：采用正交实验的方法,对气泡帷幕削减水中爆炸冲击波压力作用效果的主要影响因素进行了研究,分析了各主要影响因素的显著性,并提出了基于本实验条件下的最优因素水平组合。在实验条件下,气泡帷幕与测点之间的距离是最显著的影响因素,气泡帷幕管道的管径和流量等因素次之,孔距对气泡帷幕防护效果的影响最小。因此,在进行气泡帷幕管道设计和参数设置时,应重点关注气泡帷幕与被防护目标之间的距离和气幕管道的管径及供气气流量的变化。Effect of bubble curtain on shock wave attenuation underwater was investigated with orthogonal experiment method. The significance of each factor was discussed and the optimum factor combination from the experiment was put forward accordingly. On this experiment condition, distance between the bubble curtain and the observation point is the most significant factor,while the pipe diameter and air flow rate are the second one and the hole spacing the least one. Furthermore, the first three factors mentioned above should be paid more attention in air bubble curtain design. The method and result will be helpful to the engineering design of similar air bubble curtain.
