The discharge structure of the concrete dam is constantly subjected to the slap and vibration of the highspeed water flow during the flood discharge.The crack expansion of the old dam and the accumulated damage of the dam body caused by the flood discharge are related to the safety of the entire water conservancy project.The safety monitoring and diagnosis of the discharge structure of the dam body are important technical means to ensure the stable operation and healthy service of concrete dam.Based on the scientific research carried out in the aspects of concrete dam static and dynamic monitoring and testing technology，flow-induced vibration response analysis method，and service behavior information fusion diagnosis，the present research achievements on the flow induced response characteristics and behavior diagnosis method of concrete dam are discussed.Combined with the operation characteristics of concrete dam，the deficiencies of current research and the research fields that need to be developed and improved are discussed，in order to further improve the theoretical system of discharge induced vibration monitoring of concrete dam and provide theoretical basis and decision support for long-term service and operation management.
