摘要
对TNT炸药进行了不同装药量、不同装药位置钢筋混凝土靶中爆炸作用的模拟试验,用传感器测量了典型位置处的质点压力和质点加速度,对爆炸后效进行了观察。结果表明,装药的爆炸作用与多个因素有关,其中装药量以及埋深对其影响很大;对于直径为1m,长为1m的C-35钢筋混凝土靶,药量小于100g时,无法将其破坏;爆炸近区端面质点的加速度达到104g量级。
The simulative experiments of explosion effect in the reinforced concrete targets with different charge mass and charge positions were carried out. The particle pressure and acceleration of critical positions were measured by the sensor. The burst damage effect was observed. The results show that there are several parameters that affect the explosion effect. The charge mass and burial depth have reinforcing effect on the explosion power. The C -35 reinforced concrete targets, whose diameter and thickness both are l m, can not be completely destroyed when the charge mass was less than 100g. The quantity of particle acceleration of near field region can reach to 10^4 g.
