Dynamic Response of Parallel Overlapped Tunnel under Seismic Loading by Shaking Table Tests

Figure 14

Wavelet component of acceleration response under the action of 0.4 seismic wave. The red curve denotes the original dynamic acceleration time-domain curve, and the blue curves from top to bottom denote the wavelet components of the 1st to 8th frequency bands. (a) A4. (b) A5.
