Abstract: 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.
