摘要

为研究水下多孔爆破引起的水底和陆地震动特点，依托洋山港治理工程进行了水下多孔爆破水底和陆地震动测试试验并获得有效震动信号，利用频序小波包分解算法对震动信号进行频带分解和能量分布的对比分析。测试和分析结果表明，相比水底震动，陆地震动持续时间延长，幅值衰减很大，频带更窄，主频更低，并且含有明显的次高频带；三个方向震动能量衰减都在90%以上，而以上下垂直向能量衰减最大，水平垂直于岸的南北向衰减最小；低频带小波包能量衰减最小，高频带小波包能量衰减最大，并且水平平行于岸的东西向和水平垂直于岸的南北向小波包能量衰减呈现振荡特征。

Abstract

To study the characteristics of water bottom and land ground vibrations induced by underwater multi-hole drilling blasting, a field measurement test was conducted at Yangshan Port to get actual vibration signals. The energy distribution of vibration signals in different frequency bands was analyzed by using of the frequency order wavelet packet algorithm. Test and analysis results show that Compared to water bottom vibration, Land ground vibration attenuates greatly on amplitude and lasts longer on time, has narrower frequency band, lower dominant frequency, and higher sub-band frequency vibration. From water bottom to land ground, the vibration energy attenuate up to more than 90% in three directions, maximize in vertical direction and minimize in north-south direction. The wavelet packets energy attenuates less in low frequency band than in high frequency band and exhibit oscillatory attenuation characteristics in east-west and north-south direction.
