Discussions on some problems of dam safety monitoring system of the Ankang Hydropower Station
Kang Youcheng · Water power · 2000
The safety monitoring system of the gravity concrete dam for the Ankang Hydropower Station has been operated for many years. The actual operation found many problems in the design, such as the difference between the theory and its practice of the collimating line observation method, and the intervisibility problem in the geodetic quadrilateral design. Upon study, the Plant decided to renew and improve the existing safe monitoring system, such as deformation monitoring system, uplift pressure monitoring system, by pass seepage monitoring system, static level system, etc. These systems have been improved and good effectiveness has been gained. At present, the automation of observation system is being gradually implemented.
