Abstract
This paper discusses the method of verifying the installation azimuth of the vertical coordinate instrument for safety monitoring of arch dams during the operation period of hydropower stations.Firstly,it analyzes the problems in the operation of the arch dam vertical coordinate instrument in the safety work of the dam,and combines with the actual situation on site of the 300 meter arch dam in Jinping First Stage Hydropower Station,conducts on-site measurements on 53 vertical coordinate instruments in the 5th floor gallery of the dam.Finally,statistical analysis is conducted on the measurement results,and correction indicators for vertical coordinate instrument data are proposed.After the dam enters the operation period,the application effect of rechecking and correcting the installation azimuth of the arch dam vertical coordinate instrument is good.关键词
