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.

Using about 30000 long period seismic waveforms, which are associated with earthquakes M≥6.0 recorded by global digital seismic networks between 1980 and 1992, global Love and Rayleigh wave phase velocity variations in periods of 85s and 250s are obtained. All of waveforms are visually inspected in time and spectral domains, and the used phases are minor and major great circle phases Gl, R1, G2,and R2. Using the hybrid parameterization, in which final block inversion in higher regional resolution is embed in an aspherical reference model, and considering of the topography and crustal thickness variation, the inversions are performed with and without shallow layer corrections. Comparing with previous global phase velocity models, the l0ng wave length features are consistent both in magnitudes and variation patterns. The short period phase velocity variations are correlated with continental craton, middle cocean ridge, and tectonic activities,The correlation,however,decreases with period increases,And some oceanic hotspots are related to slow velocity anomalies.
