Abstract
Using the phase shift of reflection coefficient of SV seismic wave at the free surface of stratum, we derived the the shift time of total reflected SV seismic wave, given formulae of shift timeand drawn the curves of shift time. The results show that reflected wave of VS-wave exists negative shift;for glancing wave or angle of incidence being near the critical angle, a large shift can be caused , In other angle of incidence the shift is the same order of magnitude as the wavelength.
