| 摘 要： | 文章以马迹山港区建设工程中对山体爆破及强夯作业进行的监测数据为分析对象,对强夯振动与爆破振动信号波形进行对比,并基于小波分析方法,借助Matlab程序小波工具箱对振动信号进行多分辨率分析、频谱分析,提出了爆破与强夯激励下的地震波性质的区别.为优化爆破及强夯施工方案,减少施工中的地震波危害提供参考;为地震勘探中以强夯代替井炮作为激发源的可行性研究提供参考.

| Abstract: | The blasting and dynamic compaction monitoring data picked in the Majishan port area construction project were analyzed. Dynamic compaction vibration waveform was compared with blasting vibration waveform. Based on wavelet transform, multiresolution analysis and frequency analysis of the vibration signals were carried out by the use of wavelet toolbox in the program Matlab. The differences between the blasting and dynamic compaction seismic waves were raised. It offers references for the optimization of blasting and dynamic compaction construction and for the damage control of seismic wave in the construction. |
