摘要
通过近地表同药量的燃料空气炸药 (FAE)和 TNT爆炸地震对比试验 ,研究了炸药性能对爆炸地震波幅值的影响 .试验测试结果分析表明 ,炸药性能对地震波幅值有显著影响 ;对地震波频率影响不大 ,主频范围基本保持在 5～ 2 5 Hz.同时 ,FAE表现出了在等距离处峰值速度比 TNT高的特性 .说明
The effect of explosive characteristic on the amplitude of explosion seismic wave is studied by means of comparing experiments on ground motion caused by FAE and TNT located near the ground. The analyses of the experimental results show that explosive characteristic has a considerable effect on the amplitude of explosion seismic wave; it almost has no effect on the frequency of seismic wave. The range of main frequency is 5～25 Hz. Meantime, the maximum vibration velocity induced by FAE is higher than that by TNT at the same distance, which shows a good application prospect of FAE in martial field.
