| 摘 要： | 浅埋隧道掘进爆破振动特征有别于其他类型的爆破，作者根据浅埋隧道掘进爆破振动监测数据，拟合得到了泰山花岗岩中地面振动速度的变化规律。应用小波分析方法分析了浅埋隧道掘进爆破的振动频谱及能量分布特征。其研究对丰富地震波传播理论、指导隧道工程开挖爆破施工和保证地面建筑物安全起到了重要作用。

| Abstract: | The blasting earthquake wave of shallow tunnel differentiates that from other kind of blasting. Based on monitoring vibration data from the tunneling blasting, the characteristics of vibration from the shallow tunneling blasting are analyzed. Attenuation law of earthquake waves induced is built in this paper. With the aid of wavelet analysis approach, the method d analysis on blasting vibration signal is also established, which can be used to analyze systematically and deeply. This study will enrich the blasting earthquake wave propagation theory and play an important role in guiding the excavation blasting construction of the tunnel project and assuring the safety of ground buildings. |
