摘要
本文介绍一种仅靠一个钻孔就能确定该处岩层产状的方法。该方法是根据一个钻孔中测得的孔段方位角、天顶角及岩芯的倾角,借助于空间矢量解析法来求岩层的倾角和倾向方位角。
The paper introdues a method in which the stratum's tilt angle and tilt azimuth are determined by single bor(?)-hole. According to bore-hole section's azimuthes, zenith angles and rock core's tilt angles are surveyed in some spots of a bore-hole, and the tilt angle and tilt azimith of the stratum around the bore-hole is calculated by means of space vector. analysis.
