摘　　要：气泡帷幕削波技术的影响因素众多。为了得到气泡帷幕在实际工程应用中的最佳组合方案,利用AUTODYN软件设计3因素3水平正交试验,以冲击波峰值压力的平均削减率作为评价指标,研究了气泡帷幕层数、气泡帷幕爆心距和药包深度对气泡帷幕削波效果的影响和敏感性。结果表明:气泡帷幕的削波能力存在极大值,此后继续增加气泡帷幕层数反而会出现负效应;气泡帷幕层数对气泡帷幕削波效应的影响最大,药包深度次之,气泡帷幕爆心距的影响最小;气泡帷幕爆心距越小,药包深度越大,气泡帷幕的削波效果越好;气泡帷幕层数为2层,气泡帷幕爆心距为1 m,药包深度为10.5 m时,削波效果最好。There are many influencing factors of bubble curtain clipping technology.In order to obtain the optimal combination of bubble curtain in engineering applications,AUTODYN software was used to design a three factor and three level orthogonal test.The average reduction rate of shock wave peak pressure was used as an evaluation index to study the influence and sensitivity of the number of bubble curtain layers,the burst distance of the bubble curtain and the charge depth on the bubble curtain clipping effect.The results indicate that the clipping ability of the bubble curtain has a great value,and there will be a negative effect if the number of bubble curtain layers continues to increase.The number of bubble curtain layers has the greatest effect on the clipping ability,followed by the charge depth,and the effect of bubble curtain explosion center distance is the smallest.The smaller the burst center distance and the greater the depth of the packet,the better the bubble curtain chipping effect.When the number of bubble curtain layers is 2,the bubble curtain burst distance is 1 m,and the charge depth is 10.5 m,the clipping effect is the best.
