摘要

近区开挖爆破会引起桥梁产生振动响应,为确保桥梁安全,对爆破振动进行实时监测,并及时反馈指导爆破施工。对实测数据分析并利用db8小波基对桥墩基处振动信号进行小波分析,研究了不同频带的相对能量分布,认为爆破振动不影响桥梁的安全。
Excavation at the area near a bridge by means of blasting will cause vibration responses of the bridge.To ensure the safety of the bridge,real-time monitoring of blasting vibration was adopted and feedback was sent to guide blasting construction.According to the analysis of the measured data and by using the db8 basic wavelet to carry on the wavelet analysis in the vibration signal at the foundation of the bridge,and then through the researching of the relative energy distribution about different band of frequency,the conclusion was acquired that the blasting vibration did not affect the safety of the bridge.
