A series solution for surface motion amplification due to underground group cavities: Incident P waves
- 46 Downloads
A series solution for surface motion amplification due to underground group cavities for incident plane P waves is derived by Fourier-Bessel series expansion method. It is shown that underground group cavities significantly amplify the surface ground motion nearby. It is suggested that the effect of subways on ground motion should be considered when the subways are planned and designed.
