With the continuous growth of dam construction scale, higher requirements are put forward for long-term safe and stable operation of DAMS, but there are few studies on dam safety risk assessment at present. In order to ensure the safety of levees during service, this paper builds a safety risk assessment model of levees structure by combining VIKOR method and AHP-CRITIC method based on multi-source information such as monitoring and prediction data, changes in surrounding environment and personnel mechanical management level. Through the example verification, it can be found that the calculated comprehensive assessment results of the safety risk of the levee are consistent with the actual situation, and the accuracy of the model is verified. It can provide the safety decision scheme for managers from the macro level.
