摘　　要：介绍一种用激光准直法对尾矿坝位移进行监测的方法,采用基于三点法准直原理的激光准直和光探测器技术的尾矿坝位移监测系统。利用激光的方向性强,亮度高和单色性等优点,在固定工作基点上的光电探测器上获取光斑,通过求取像点中心位置,进而得到大坝的变形。该方法具有精度高,可同时对尾矿坝的水平位移和垂直位移进行检测的优点。A laser collimating automatic method for monitoring the deformation of tailing dams is proposed. The principle and application of the laser collimate are based on the three point method collimation principle and the photo-detector technology. Using the laser＇s advantage such as good direct, high brightness and monochromaticity, a fixed CCD camera is used to capture the images of spot and the computer calculated the central point of the images automatically and precisely. Merits of the system are with high accuracy, vertical and horizontal deformation measurement simultaneous.
