利用封闭化爆模拟地下核爆冲击震动效应的研究

Simulation of shock and vibration of underground nuclear explosion based on enclosed chemical explosion

地下核爆冲击震动效应分析是防护工程的重点问题之一。从地下核爆的冲击震动效应与封闭化爆的冲击震动效应的相似性出发，利用爆炸能量相似原理和封闭化爆冲击震动效应的评估方法，对地下核爆冲击震动效应进行了分析。结果表明：封闭化爆与地下核爆冲击震动效应之间的有效当量系数在11％～19％之间，地下核爆的冲击震动效应可以用封闭化爆近似模拟。

Analysis of shock and vibration of underground nuclear explosion is one important study of protection en gineering. Shock and vibration of underground nuclear explosion has been analyzed on the basis of similarity be tween underground nuclear and chemical explosion. This has used the blasting similarity law and features of chemi cal explosion. The results show that the equivalent weight coefficient between enclosed chemical explosion and un derground nuclear explosion is in the range of 11% to 19%. Simulation of the underground nuclear explosion through enclosed chemical explosion is applicative.
