| 摘 要： | 采用爆炸相似理论计算了JH-14装药水下爆炸冲击波的k值和峰值压力，根据计算结果设计了试验方案。测试了JH-14炸药在不同水深及作用距离处的冲击波峰值压力，用最小二乘法对测试结果进行线性回归，拟合出JH-14炸药爆炸冲击波超压系数k为57.01、α为1.131，该值可作为产品设计的依据。

| Abstract: | In this paper, k-value and peak pressure of underwater explosion shock wave of JH-14 charge was calculated according to the theory of explosion similarity. Test scheme was developed according to the calculation. Peak pressure of JH-14 charge at different depths and distances of action were tested, and least square method was used in linear regression of test result. By the proposed calculation of JH-14 charge, shock wave overpressure coefficient k is 57.01 and α is 1.131, which could be used as the basis for production design. |

| Keywords: | JH-14 charge shock wave peak pressure overpressure coefficient operating distance |
