The reservoir dam disaster is characterized by its suddenness, and the consequences of dam failure are unbearable for people.In order to accurately understand and determine the severity of the consequences of reservoir dam failure, and to ensure the safety and interests of downstream public, this paper comprehensively evaluates the consequences of small and medium-sized earth-rock dams' failure based on the current research status.In this paper, the combination weighting method is used to calculate subjective and objective weights, which not only compensates for the shortcomings of subjective and objective weights but also considers the advantages of both.To ensure that the information of subjective and objective weights is not lost, the minimum information discrimination principle is adopted to determine the comprehensive weight.By combining the advantages of uncertainty inference of the cloud model and the qualitative and quantitative analysis of extensible matter-element theory, a comprehensive evaluation model of extensible cloud dam failure consequences based on combined weighting is constructed.The effectiveness and applicability of the model are verified by using small and medium-sized reservoirs' data to evaluate the severity of reservoir dam failure consequences.
