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.
