摘要(Abstract)：

近区隧道开挖爆破会引起大坝产生振动响应,为确保大坝安全,对爆破振动进行监测分析,及时反馈指导爆破施工。利用db8小波基对坝基处振动信号进行小波分析,结果表明采用db8小波基处理爆破振动信号是可行的,爆破能量分布主要集中于15.625～250.000Hz频带之间,而非大坝基频所在的频带,最终得出爆破振动对大坝安全影响较小的结论,为同类工程提供参考。
Tunnel excavation blasting near a dam will cause vibration response,thus to ensure safety of the dam monitoring analysis for blasting vibration has been done in order to feedback blasting construction in time.By using of the db8 wavelet basis to analyze the vibration signal at the dam foundation,and the results showed that this method was feasible.The mainly distribution of blasting energy ranged from 15.625 to 250Hz,which not the frequency band of the dam foundation.Finally,the conclusion was acquired that the blasting vibration had little influence on the safety of the dam,and thus could provide a reference for similar projects.
