摘要
在对地下核爆炸冲击震动效应分析的基础上,对地下核爆炸的冲击震动效应的模拟方法进行了探讨,对封闭化学爆炸的冲击震动效应进行了计算。结果表明:地下核爆炸冲击震动的应力波峰值、质点的速度、质点的加速度和质点位移,都可以用封闭化学爆炸来进行模拟,而且封闭化学爆炸与地下核爆炸之间的有效当量系数在6%～30%之间,这与已知的有效当量系数基本吻合。结论:地下核爆炸的冲击震动效应可以用封闭化学爆炸近似模拟,将会给地下核爆炸的研究带来极大方便。
Based on shock and vibration effect of underground nuclear explosion,the simulation method of shock and vibration effect and the enclosed chemical explosion effect were studied.Results show that the peak value of stress wave,peak particle velocity and acceleration and displacement of the underground nuclear explosion could be simulated through enclosed chemical explosion.The equivalent weight coefficient between enclosed chemical explosion and underground nuclear explosion was 6%~30%,in agreement well with the known equivalent weight coefficient.Therefore,the enclosed chemical explosion can be used to simulate the underground nuclear explosion.
