Optimization Method of Sight Line Observation for Long-distance Concrete Dam under Complex Observation Conditions
In order to solve the problem that the sight line observation accuracy of long-distance concrete dam under complex observation conditions does not meet the requirements of the specification,a"segmented opposite small an-gle method"based on high-precision measurement robots and positive and negative monitoring data is proposed.Through the analysis of trial operation observation data,the displacement amplitude of each measuring point con-forms to the deformation law of the dam,and the correlation between the displacement and the air temperature and water level is related to the location of the monitoring point.The observation accuracy analysis shows that this method can meet the observation accuracy requirement of 1mm,so the"fully automatic segmented opposite small angle method"provides an effective way to improve the sight line observation accuracy of long-distance concrete dams.
