| Abstract: | Taking transverse wave velocity of elastic wave as a parameter, using fast scalar transferring arithmetic of dispersion curves of Rayleigh surface wave to operate forward modeling calculation, the study has systematically investigated the effect on base model dispersion curves of Rayleigh wave caused by thickness of soft and weak sandwich, and analyzed and concluded the changing rules of frequency and phase velocity （f- c）, frequency and wave velocity （f-k）, depth and phase velocity （h-c） and other base model curves of Rayleigh surface wave with different thickness of soft and weak sandwich. |
| Keywords: | dispersion curves of Rayleigh wave forward modeling thickness of sandwich changing rules |
