Wavelet Packet Analysis of Blasting Vibration Caused by Small Interval Tunnel of Large Span

摘要：

On the basis of the vibration monitoring data, the dynamic characteristic of the small interval tunnel of large span under blasting loads was researched. The wavelet packet theory was applied to analyze the spectrum and energy transformation law of the quake wave caused by blasting spreading along the rock slope. The frequency spectrum feature, main vibration frequency and energy distribution according to the distance, peak particle velocity in different frequency-band, and energy distribution law in the spreading of the blasting quake wave along the rock slope were concluded. The conclusions are very significant for the further study on the dynamic stability of the high rock slope.
