英文摘要：

For a super-large hydraulic complex, comprehensive regulation is complicated due to flood control, power generation and ship navigation, and it is difficuh to ensure the security in this situation. In order to solve the safety operation problems and satisfy the demands of long-term safety operation for large hydraulic complex,this project summarizes three common scientific technology problems in this field on the basis of research progresses and engineering practice in the world ： 1 ） hydraulic disaster-causing mechanism of high speed flow, high pressure transient flow and high head seepage, operation response and performance attenuation of dam and reservoir banks under the complicated operating conditions ;2）safety control index and comprehensive safety evaluation theory of hydraulic com- plex operation;3 ）new monitor and detection technology and equipment of multiple factors considering coupling effects on safety opera- tion. Faced the specific safety problems of hydraulic complex, five frontier technologies need to be broken through urgently ： 1 ） real-time operation technology of flood control and discharge safety ;2 ）safety and intelligence operation technology of hydro-power system;3 ）combined optimal control technology of power generation,flood discharge and ship navigation ;4）risk control and safety technology in the initial stage of hydraulic complex operation ; 5 ） long-term operation technology for safety of high dam structure and stability of reservoir bank under the complicated operating conditions. At last, the future research of control and safety operation for super-large hydraulic complex should be around the innovation of theoretical approach, detection equipment, security technology of hydraulic complex, realtime operation technology and system integration technology.
