地质剖面图上的钻孔弯曲线,通常是根据测定的方位、倾角和测斜深度用图解法绘制.其缺点是作图精度不高,工效又低,同时经常要用橡皮擦拭,影响图面清洁美观.为此,我们曾采用计算法展点作图,但计算较费时,又难以掌握,并常发生差错.最近,我们编制了“钻孔弯曲计算诺模图”(见插页),可直接查取钻孔任一线段在勘探线上的投影距b和投影于垂直线上的投影距c及深度修正值△L等(图1).此法作图方便,精度较高,试用效果较好.
The drilling curve on the geological profile is usually plotted according to the measured azimuth, inclination and inclinometer depth.The disadvantage is that the mapping accuracy is not high, the work efficiency is low, and the eraser is often used to wipe the surface Clean and beautiful. For this reason, we used to calculate the method of drawing points, but the calculation is more time-consuming and difficult to grasp, and often mistakes.We recently compiled a , Which can directly check the projection distance b of any line segment on the exploration line and the projection distance c and the depth correction value △ L projected on the vertical line (Figure 1). This method is convenient for drawing and has higher accuracy, Trial effect is better.
