Aiming at issues in operational behavior monitoring of large hydropower dams
the full process monitoring concept and methodology are developed based on case analysis and theoretical analysis. Firstly
by review of dam failure cases and damage theories
the macroscopic responses of dams during the initiation and development of structural anomalies are analyzed
revealing the evolution patterns of operational behavior throughout the entire dam failure process. On this basis
by integrating pattern monitoring with operational status monitoring
the full process monitoring concept is established
with precise characterization of the full-process anomaly features as its core. Finally
a monitoring indicator system comprising change patterns and features monitoring thresholds is constructed
and a state equation for dam operational behavior monitoring is proposed
along with a three-level early warning rule system. Case analysis demonstrates that the monitoring and early warning method based on the full process monitoring concept can accurately identify the anomalous stages of dam operation
with warning points occurring earlier compared to traditional methods
thereby effectively enhancing the risk prevention
control
and emergency response capabilities of large hydropower dams in operation.
