摘要
讨论了不同孔段组合条件下地下岩层产状的计算方法,全面而且精确地再现赤平极射投影的图解结果:对双斜孔段组合能够求出所有可能的产状解(包括逆向穿层解);对直斜孔段组合、三斜孔段组合、连续多斜孔段组合,以及双斜孔段组合中具同向穿层单解的计算对象能够给出最可能的产状解。
Methods for measuring underground formation occurrence under different formation combination are stud- ied, and overall and accurate graphic results gained by sterogeographic projection are showed in this paper. All possible occrrence results in double downward hole formation ( including incongruous tranverse graphic results) ; and most possible occurrence graphic results in direct downward hole formation, tri - downward hole formation, serial multi -downward holes formations and concordant single graphic result in double downward hole formation can be measured.
