真空激光准直系统在金安桥水电站变形监测的应用

The Application of Vacuum Laser Alignment System in Deformation Monitoring of Jin'an Bridge Hydropower Station

真空激光准直系统是我国自行研制的具有高精度且能同时观测水平位移和垂直位移的监测仪器。研究重点介绍了金安桥水电站大坝真空激光准直系统的系统组成和系统工作原理。在大坝坝顶左岸、坝顶右岸及廊道布置真空激光准直系统,通过对这些测点的位移数据收集,及时准确地反应了大坝位移的情况,能够实现对大坝坝顶左岸、坝顶右岸及廊道的监测,取得了良好的效果。作为新兴的监测手段,激光系统设备在监测中发挥了其时效性强、监测变量多、精度较高等特点,能够很好地实现大坝水平和垂直位移同步自动监测,具有很高的实用价值。

Vacuum laser alignment System researched by our country ourselves is a monitoring instrument which has high precision and can observe horizontal displacement and vertical displacement.In this text,we introduce the composition and work principle of Jin＇an bridge hydropower station vacuum laser alignment system.The vacuum laser alignment system is laid out on the left bank and right bank of the dam and in gallery,and we can understand the displacement of the dam precisely and on time,monitor the left and right bank of the dam and gallery by collecting data from these points.We have achieved good results.As a new monitoring means,the laser system play the effect of strong timeliness,more monitoring variables and high precision,so that it can automatically monitor horizontal and vertical displacement very well,having high practical value.
