Analysis on abnormal operation of static leveling system for dam foundation of Daheiting reser-voir
The static leveling system for dam foundation of Daheiting reservoir has been in operation for nearly 20 years.During operation,abnormal values were detected at measuring points.Through the mon-itoring system test,on-site and monitoring data inspection,and manual observation data comparison and analysis,comprehensive analysis and study of the abnormal conditions existing in operation are con-ducted to find out the cause reasons,and it is determined that the vertical displacement of dam founda-tion is normal and the dam body is operating stably,which can be used for reference to similar projects.
