The transversely isotropic layered elastic model is used to simulate the layered space above the half space and the artificial transmissive boundary is used instead of the half space to absorb the energy. The ring-shaped vertical and horizontal harmonic loads on any facet are given by the thin-layer element method The displacing formula of the next field is derived and the displacement response of the arbitrary section of this kind of site under vertical and horizontal harmonic loads is derived. The results show that the proposed method is similar to the theoretical solution and the transverse isotropic The nature of the Green function has a significant impact
