The converted-wave time curve is non-hyperbolic and becomes more complex in anisotropic media. This paper has mainly discussed the method for anisotropic velocity analysis of PSV wave and conducted a velocity analysis of converted-wave in one-parameter method based on previous research results. As the velocity analysis of PSV wave is not independent from PP wave data, the authors made use of efficient information on PP wave data, simplified the procedure of velocity analysis and obtained the information of velocity and anisotropic parameters. To some extent, the authors' study improves the accuracy and efficiency and proves to be effective, as shown by the results of the model test.
