燃料空气炸药爆炸地面振动的幅值特征研究
|
摘要
对燃料空气炸药爆炸 (FAE)爆炸时所引起的地面振动幅值特征提出了研究。在相同装药量和场地条件下 ,进行了 FAE与 TNT炸药爆炸地震效应的对比实验 ,得到了地面竖向振动的时间历史记录结果。分析表明 ,FAE爆炸所产生的地震效应具有更高的峰值强度。所得到的研究结果对认识 FAE爆炸力学效应具有一定的指导价值
Amplitude characteristics of ground vibration caused by fuel air explosive(FAE)explosion are studied in this paper. Under the identical charge mass and experimental field conditions, experiments are done to make comparison between the explosion seismic effects caused by FAE and TNT explosive, obtaining time histories of vertical ground vibrations. From the analysis of experimental results, it shows that FAE explosion produces much higher peak particle strength of the seismic effect .The presented result provides very useful knowledge to learn the mechanics effect caused by FAE explosion.
