摘要(Abstract):

为了检验不同构筑方式的快速拼装式防爆墙组合防护性能,利用皮卡车承载602 kg TNT制作的汽车炸弹进行实爆来模拟恐怖袭击。试验表明:汽车炸弹爆炸对墙后目标的破坏作用主要是由于顶部绕射的冲击波造成的,其消波性能的主要影响因素是墙体高度,且当墙体布设高度大于2 m时,防爆墙的消波效应可达81%以上,同时,在墙后1~2.5倍墙高处增设一道消波墙,可提高防爆墙的消波效应;防爆墙对墙后活体目标具有较好的防护能力,能有效抵抗汽车炸弹的袭击损伤。
In order to test the combined protective performance of rapid assem bling anti-blast walls with different construction methods, the truck carrying 602 kg TNT was used to simulate the terrorist attack of car bomb. Test shows that the car bomb damage to the target behind the wall is mainly caused by the top diffraction wave, and the wave dissipation performance are mainly affected by the height of the wall. When the wall height is greater than 2 m, the anti-wave effect of the anti-blast wall can reach more than 81%.At the same time, add a wave dissipating wall at the height of 1-2.5 times behind the wall, which can improve the wave dissipating effect of the anti-blast wall.The anti-blast wall has good protected ability to the living target behind the wall and can effectively resist the attack damage of car bomb.
