摘要
The exploration of Rayleigh surface wave aimed at effectively using dispersion curves to inverse the shear wave velocity and depth of stratum, but sensitivity of each mode with the shear wave velocity and depth of stratum are different. The sensitivity of each mode of Rayleigh wave with the shear wave velocity and depth of stratum of every layer is analyzed and discussed. Experimental results show that fundamental mode is more sensitive to the shear wave velocity and depth of stratum of shallow layer, and sensitive areas mainly concentrate on the narrow frequency range. The results can provide a theoretical basis for the multi-mode joint inversion of rayleigh surface waves.
