摘要:
为了研究不同起爆顺序对爆破振动的影响，通过设置不同测点对大量的微差爆破进行了振动监测。监测数据回归及小波包分析发现：不同的起爆顺序下，爆破抛掷方向不同，爆破抛掷反方向的振动强度最大。不同方向上的爆破地震波主频大小以及振动信号的频带能量分布均具有规律性；爆破抛掷反方向15Hz以内频带所占比例明显高于其他方向，反方向上产生的爆破地震波对周围结构危害相对较大。
Abstract:
The vibration monitoring was conducted by setting different measurement points for a series of millisecond blasting to study the blasting vibration under different initiation sequence. The corresponding data regression and wavelet packet analysis show that the maximum vibration intensity is along the reverse direction of blasting throwing, which changes with the blasting sequence. The blasting seismic wave frequency in the different directions and frequency band energy distribution of vibration signal have some regularity; The proportion of blasting vibration within 15Hz band in blasting throwing reverse direction is obviously higher than in the other directions, and the blasting seismic wave in throwing reverse direction has the larger harm on the surrounding structures.
