Wavelet Analysis on the Vibration of Large Dock Caused by Reef Blasting Underwater
This paper is based on the vibration monitoring from blasting of the reef underwater near a large dock. Applying wavelet packet transform method to analyses the blast vibration signals collecting from different monitoring positions, the distributed characteristic frequency of the docks part was brought forward. Moreover, from analysis of die amplitude of the three vibration components, Conclusion was drew that only the vertical component of the vibration increasing along with the height of the structure.
