| 摘 要： | 为研究装药壳体厚度对混凝土毁伤效果的影响,设计了不同厚度壳体装药和无边界效应的混凝土靶板,并进行了实验.实验结果表明,在壳体厚度较小时,爆坑体积比裸装药炸药时的爆坑体积大;当壳体厚度增大时,爆坑体积呈下降趋势.随着壳体厚度的增加,壳体破碎性下降.通过空气冲击波超压测试,并结合经验公式计算了形成空气冲击波的能量占炸药爆炸总能量的比例.

| Abstract: | In order to investigate the influence of shell thickness of explosives on damage effect in concretes,the explosives with different thickness shells and concrete targets with non-boundary effect were designed.Experimental results show that the craters volume caused by explosives with thin shell is more than the craters volume produced by no shell explosives,but the sizes of craters decrease with shell thickness increasing.The fragmentized degree of shells descends with shell thickness increasing.The ratios o... |
