摘要
通过实验,分析了水压爆破接触爆炸作用于底部固壁不同部位的超压分布,指出了现接触爆炸超压计算公式在距爆源的距离较大时,其计算误差较大,必须采用声学近似原理进行估算。
By way of experiment, we analyzed the excess pressure distribution at the different position of the bottom when contact explosion occurred under water, and pointed out that the calculation formula of contact explosion's excess pressure at a great distance to explosion source has a comparatively great error, so the approximate principle of acoustics must be used.
