摘　　要：介绍了NJG型真空激光准直系统的基本原理以及在潘家口水库大坝的布置情况。在目前的实际工作中,NJG型真空激光准直系统能够实现水平位移与垂直位移的自动化同步监测,测量结果均符合大坝变形监测的规律,数据稳定且连续。通过分析和研究最近2 a NJG型真空激光准直系统的观测资料,确认NJG型真空激光准直系统的可靠性,其平均无故障时间和自动化数据缺失率均符合规范要求,由此得出应用于大坝变形监测中的NJG型真空激光准直系统具有精度高、故障率低、运行稳定、方便维护的特点。This paper introduces the basic principle of NJG vacuum laser collimation system and its layout in the Panjiakou Reservoir Dam. In practical work,NJG vacuum laser collimation system can realize the automatic and synchronous monitoring of horizontal and vertical displacement. The measurement results are consistent with the law of dam deformation monitoring,and the data are stable and continuous. By analyzing and studying the observation data in recent two years,the reliability of NJG vacuum laser collimating system is confirmed,and its average fail-free time and automatic data loss rate meet the specification requirements. Thereofre,it is concluded that NJG vacuum laser collimation system applied to dam deformation monitoring has the characteristics of high precision,low failure rate,stable operation and convenient maintenance.
