【Abstract】 Based on the fact that in situ Rayleigh surface wave phase velocities are mainly controlled by shear wave velocities in soils and that the partial derivative of Rayleigh surface wave phase velocities with respect to shear wave velocities varies regularly according to the depth of soil, combining the stripping method used in geophysical exploration and the half wave length method used in engineering geological exploration, this paper puts forward a new method of using the data of surface wave phase velocities to inverse shear wave velocity of soil layers. The accuracy of the suggested method has been verified by the observed data in field shear wave velocity test.更多还原
