摘　　要：提出用半导体激光发射器结合位敏传感器进行位移测量和利用光学测角仪进行倾角观测的方法解决拱坝变形观测问题。对激光监测自动化系统进行了原理分析、算法推导、精度评定。在白山拱坝的实践表明 :本系统精度高 ,自动化效果好 。The method for arch dam deformation measuring that the displacement is measured by PSD with laser emitter and the angles are measured by optical instrument is brought forward in this paper,and the principle of laser monitoring is analyzed and the calculating method is derived,the precision is estimated as well.The example at Baishan arch dam indicates that the system has high precision and good effect of automatization,so it can be applied widely.
