本文利用空间解析几何及矢量代数的方法,从理论上分析了地震深度剖面中断层线与水平线的夹角(即断层线在深度剖面中的倾角)与断面真倾角、反射界面真倾角以及测线方向之间的关系。最后,根据本文观点对测线布设及资料解释等实际工作提出了相应的建议。

In this paper the relationship between fault-line dip on seismic depth, section and the real dip of fault plane, real dip of reflection interface, as well as the orientation of seismic line is theoretically analyzed by means of spatial analytic geometry and vector algebra. Lastly,from the author's viewpoint, suggestions related to practical work involving the layout of seismic line and the data interpretation are made respectively.
