分析结果表明，在单段与多段微差爆破中，不同结构体对爆破震动的响应显著不同；
The results show that response characteristics of vibration induced by single deck and multi-deck blasting have marked differences.
由于隧道开挖采用多段微差爆破，所以多数实测爆破地震波中存在多个优势频率峰值，能量带分布很宽。
Multi-millisecond blasting is used in tunnel excavation, so there are several dominating frequency peak values in actual observation blasting seismic, and the energy distribution belt is wide.
