%X The formulas of three dynamic boundary conditions of transversely isotropic stratified media are derived. And the methods how to combine them with the discretized algebraic eigenvalue equation for generalized Rayleigh and Love waves are also given. The dynamic responses of the media with these different boundary conditions to concentrative harmonic loads are evaluated and compared with the theoretical results. Through the comparison, it can be found that the responses of the media with damping and half space boundary conditions when the media are thick, are close to the theoretical ones. But for the fixed boundary condition, only the responses of upper soil layers are close to theoretical ones. The results near the bottom of soil layers are much different from those for damping and half space boundary conditions. According to the evaluation, the applicable ranges for these boundary conditions are suggested.
