近地面云雾爆轰地震波的幅频特性

Amplitude Frequency Characteristics of Seismic Event Caused by the Near-ground Cloud Detonation

为了更好地认识FAE爆炸作用的特点,适应该类爆炸现象综合评估的要求,文中通过实验研究了近地面FAE爆炸地震波的特征。研究表明:在一定的实验条件下,装药量相同的FAE爆炸地震波比TNT爆炸地震波具有更高的强度,其地面运动持续时间相当,而加速度频谱趋向于更高更宽的频率范围。

In order to understand the characteristics of FAE explosion effect and meet the request of synthesis evaluation for this type explosion phenomena, the characteristics of nearground FAE explosion seismic wave is studied by experiment method. It shows that FAE explosion produces much higher peak particle strength of the seismic effect than TNT explosion for the same experiment condition and explosive load, the duration of the ground movement is comparative and the frequency range of the acceleration frequency spectrum trends towards much higher and wider.
