摘　　要：地震观测中越来越多地采用深井观测技术。本文对深井观测系统中井对地震波的影响进行讨论,得到:在地震波频段里,井的存在对井中三分向地震仪的水平分量没影响,只是在一个比较有限的范围内对垂直分量有一定影响。在一级近似下,深井观测与地表观测地震波的差别是因地震仪被放置的位置不同所致。 这一结果将有助于深井观测资料与地面观测资料的统一使用。It has been increasingly tendency in adoptione the deep bore-hole technique for seismic observation . This paper deals with the affect of the bore-hole on seismic waves in the deep bore-hole system and obtains the conclusion that the existence of a bore-hole makes no affect on the horizontal component of a three component seismometer in bore-hole at the frequency range of seismic waves . It makes only a limited affect on the vertical component. To the first approximation the difference between bore-hole record and ground-surface record of seismic waves is caused by the different places of seismometer deployment.This conclusion is useful in unified utilization of bore-hole records and ground records of seismic waves.
