本程序可对一个钻孔连续三次进尺资料的计算,确定在该三次进尺内地下岩层的产状。具速度快、精度高和使用方便的优点,并对在三次进尺内岩层产状有逐渐变化和在度量数据时的人为误差具有一定的处理和纠正能力。例1某钻孔连续三次进尺的数据见表1。该实例在三次进尺内岩层产状逐渐变缓,在赤平投影图上三个小圆既不相交也不相切,需要人为取折中值作为产状。本程序
The program can drill a hole three times in a row footage calculation to determine the formation of the underground rock formation within the three footage. The invention has the advantages of fast speed, high precision and convenient use, and has the ability of processing and correcting the gradual change of the rock formation in three times of footage and the human error in measuring the data. Example 1 A drilling three consecutive footage of the data in Table 1. In this case, the formation of the rock formation gradually becomes slow within three dimensions, and the three small circles neither intersect nor tangent in the stereographic projection, and the artificial median value is needed as the origin. This procedure
