| 摘 要： | 根据钻孔资料确定地下岩层产状是一个比较复杂的问题。利用赤平极射投影网上的小圆相交方法,可以求得倾斜钻孔资料地下岩层的可能产状,但赤平极射投影网上的小圆作图比较复杂。利用通用地质坐标系可直接在球面投影上计算出两个小圆的交点,能更快更准确地得到结果。

| Abstract: | Determination of attitude of blind rocks from data of drilling is a more comlicated task. The attitude of blind rocks can be calculated in terms of point of intersection of small circles in steregraphic projection net, but drawing small circles is more complex. The point of intersection of small circles on spherical projection can be calculated in terms of general gelolgical coordinate sysytem, therefore more accurate and quick result can be obtained. |
