封闭式爆炸容器小药量爆炸振动效应研究

Research on Vibration Effect of Small Quantity Explosive in Closed Blast Vessel

为评估炸药在封闭容器内爆炸产生的振动效应对周围环境的影响，对封闭式爆炸容器小药量TNT炸药爆炸产生的爆炸振动效应进行了爆源邻近实地监测和测试。结果表明：小药量炸药爆炸引起的爆炸振动效应对距爆源100m以外的普通砖结构民用住宅产生的速度强度远低于其临界峰值速度，不会对其结构产生明显影响。

In order to study how the vibration effect of explosion in confined vessel influences its surroundings, this paper discusses the vibration effect of small quantity explosion （TNT） and we monitored and measured this blast in the confined vessel on the spot. From the experiment we draw a conclusion. The vibration effect caused by the explosion of the small quantity explosive can not have an obvious effect on the bricky housing which situates more than 100 meters away from the detonating spot because the velocity of the vibration cannot reach its critical crest velocity.
