[VI-296] Risk Evaluation for Tunnel Cutting Face Condition by using Blasting Sound and Seismic Wave
Keywords:Tunnel, Blasting Sound, Seismic Wave, FFT Analysis, Risk Evaluation
The power spectrum frequency was calculated by FFT analysis on blasting sound and elastic wave for TFT survey in a tunnel. As a result, it was confirmed that the power spectrum of blasting sound and elastic wave changed with the change of geology and support pattern. In addition, it was also confirmed that when the receiving point was relocated, the power spectral frequency of blasting sound and elastic wave changed even if the geology and support pattern were the same.
As the results, blasting sound and elastic wave are able to use for risk evaluation of tunnel cutting face.
