摘要
Abstract
The problems of traditional geodetic survey are high safety risks,high observation costs and long ob-servation period,which can not reflect the working behavior and safety state of hydraulic structure in time.On the contrary,the external deformation monitoring automation system(GNSS)can improve the monitoring effi-ciency,save costs,reduce safety risks and meet the needs of modernization and intelligence,so it is necessary to automate the dam appearance deformation observation.After the automatic reconstruction of a project,it is found that the difference between the monitoring data and the manual data is large.Through the comparison and statistical correlation analysis of the data,it is found that the GNSS high-elevation data is significantly af-fected by the change of daily temperature,and it has a moderate correlation with the rainfall data,and had a weak correlation with the reservoir water level.关键词
