Abstract: First of all, based on the theoretical crustal model, the feasibility and reliability of using the radial and transverse receiver functions to jointly invert the crustal anisotropy program are analyzed. Then the program is applied to the actual analysis of the receiver functions of Yugan seismic station. The results show that the polarization direction and time delay of the fast wave calculated by different objective functions are different. The joint objective function shows that the fast wave direction of Yugan seismic station is about 79° and the time delay is about 0.19 s.
