Abstract: In the upper and middle reaches of the Yangtze River, undesirable hydraulic characteristics and structural damage caused by flood discharge have emerged in some large-scale hydraulic projects. Characteristics of response to safety regulation are studied for flood discharge structures and other structures at the damsite. The disaster-causing mechanism of flood discharge damage is revealed, and the precise regulation technology is developed to reduce the threat of flood discharge. An intelligent and fast evaluation method is proposed, and a flood discharge safety monitoring and real-time operation system is established. The above evaluation method and monitoring system can be used for real-time monitoring, prediction, evaluation and optimization scheduling of flood discharge and energy dissipation protection, cavitation erosion, structural and field vibration, atomization and other response characteristics. The findings and corresponding technologies proposed in this study provide a well guidance for similar projects.
