摘　　要：基于宁波市轨道交通1号线二期育王岭隧道工程,围绕轻轨隧道开挖施工引起的爆破振动,对其进行安全监测和结果分析,得到相应的质点振动速度峰值衰减经验公式以及爆破振动幅频特性,保证轻轨隧道爆破施工质量与安全,有效保护既有建构筑物的安全。研究得出的结论与建议可供同类地区类似工程参考与借鉴。Based on Ningbo Rail Transit Line 1 Phase II Yu Wang Ling tunnel project, the blasting vibration characteristics was studied around blasting vibration controlling during light rail tunnelling, through blasting vibration safety monitoring and its result analyzing. The attenuation empirical formula of corresponding peak particle velocity and the amplitude - frequency characteristics of blasting vibration, have been obtained by above analysis, which ensure the quality and safety of the supporting light rail tunnelling, and the around buildings and structures have been protected too. The conclusions and recommendations obtained from above study could be referenced during similar projects from similar area.
