摘　　要：针对胶州湾海底隧道青岛端接线工程匝道开挖对主隧道的振动影响,在主隧道内进行爆破振动监测。以实测振速数据为依据,分析主隧道内对应匝道工作面前后震动波的传播规律,得到垂直振速、水平径向振速以及水平切向振速随测点距工作面距离不同的变化规律。分析发现,主隧道内已开挖区爆破振速大于未开挖区振速,未开挖区振速在一定范围内相对稳定。In order to study the Vibration influence on Jiaozhou Bay Sub-sea Tunnel induced by the blasting in the ramp tunnel, blasting vibration monitoring is made in the main tunnel. The propagation rules of vibration waves in the main tunnel are analyzed on basis of the measured vibration data. The propagation rules of the vibration velocity are obtained. The analysis shows that the b unexcavated section and that lasting vibration velocity in the excavated section of the main tunnel is larger than that in the vibration velocity in the unexcavated section is stable in certain range.
