摘要：

利用反射波相角推导出了反射P波在反射界面的横向偏移和横向偏移渡越时间,讨论了Goos-Hanchen效应对P波正常时差所造成的影响。结果发现,对于掠入射波或当入射角在临界角附近时,反射P波的Goos-Hanchen效应较为明显,故在实际的地震资料处理中应进行横向偏移效应的误差校正。

Abstract:

The influence of the Goos-Hanchen effect on the P wave normal time lag is studied using reflection wave phase derived from the lateral offset of P wave in the reflector and the lateral offset transit time.Results show that for incident wave or when the incident angle in the vicinity of the critical angle,the Goos-Hanchen effect P of wave is obvious.So in the actual seismic data processing,error correction of the lateral offset effect should be made.

Key words: Goos Hanchen;seismic wave;transverse offset;total reflection
