%X Using the phase shift of reflection coefficient of SH seismic wave at the interface of strata, we derived the lateral shift and group time delay of total reflected SH seismic wave, given formulae of normal moveout of Goos-H nchen effect, discussed the influence of Goos-H nchen effect on normal moveout of SH-wave, and drawn the curves of lateral shift, group time delay, normal moveout of Goos-H nchen effect and error of normal moveout caused by Goos-H nchen effect with respect to the angle of incidence. The results show that for glancing wave or angle of incidence being near the critical angle, the lateral shift and group time delay are very large. A large error can be caused by Goos-H nchen effect; In other angle of incidence the lateral shift(group time delay) is the same order of magnitude as the wavelength (period); So Goos-H nchen effect can bring about large influence on the travel time of SH-wave. The error correction of Goos-H nchen effect should be made before seismic data processing.
