利用三维模型快速求解岩层产状的方法

A 3D-model-based Method of Quick Calculation of Rock Orientation

岩层产状一般可利用机械罗盘或电子罗盘进行测量,当岩层位于高陡地段,无法手持罗盘进行测量时可采用三点法,即通过全站仪或其它测量手段测量岩层面上不在同一直线上的3个点来求解岩层产状.传统的三点法一般通过公式计算求得产状,求解过程繁琐,不直观.本文研究了一种利用三维模型快速求解岩层产状的方法,并利用公式法进行了验算,验算结果表明三维模型求解岩层产状的方法直观简单,结果可靠.

The rock orientation is generally obtained by mechanical or electrical compass. When the rock layers occurred at high and steep area, 3-points method is applied instead of on-site measuring by handheld compass. This method needs to measure 3 points, with Electronic Total Station or other instruments, which are not on the same line, and then calculates the orientation by traditional formula, is actually a complicated and non-intuitive process. A new method by using the 3-D model to quickly resolve the orientation is proposed in this paper. This paper proposes a 3D-model-based method for a quick calculation of rock layer occurrence, the result of which is checked with the formula. The verification show this proposed method is simpler and reliable, as also reliable for calculation of rock orientation.
