激光测距仪在高陡边坡结构面产状测量中的应用

Applications of Laser Range Finder in the Measurement of the Attitude of Structural Planes in High and Steep Slope

激光测距仪是利用激光对目标的距离进行准确测定的仪器,被广泛的应用于光学和测绘领域中。而结构面产状通常是采用地质罗盘进行测量,边坡高陡时往往难于测取。在对激光测距仪的功能进行简单介绍后,分析了利用其测量结构面产状的原理,并推导了产状计算的公式。通过实测产状数据与计算数据的对比及误差分析,验证了计算结果的可靠性,说明激光测距仪可用于高陡边坡结构面产状的测量和计算,并将这一成果应用于结构面产状的量测中,取得了较好的效果。这种非接触的测算方法是对传统地质工作中产状测量方式的一种改进和创新。

Laser range finder is an apparatus which measures the distance of the target accurately by laser, and it has been widely used in the field of optics and surveying and mapping. The attitude of the structural planes are usu- ally measured by compass, but on high and steep slopes are often difficult to take measurements. After a brief intro- duction of the instrument＇ s features, this paper analyzed the principle of using this device to measure the attitude of the structural planes, and derived the formula of the occurrence calculation. By thc contrast of the measured and calculated data and the error analysis, we can draw the conclusion that the calculation results is reliable, and the laser range finder can be used for the attitude measurement of structural planes in high and steep slope. And the a- chievements have been applied to the measurement of sructural planes and have achieved good results. This non - contact measurement method is an improvement and innovation to the traditional geological work.
