- •
The amplification patterns of the ground surface caused by twin tunnels are evaluated.
- •
The time-domain BE technique is developed for seismic ground response analyses.
- •
Variations of amplification values versus depth and distance of twin tunnels have been shown.
- •
The amplification patterns are essentially controlled by wavelength of the incident waves.
- •
Some site coefficients are presented for modification of seismic microzonation studies.
