To scientifically evaluate the severity of dam-break consequences and determine risk man-agement priorities,and a comprehensive assessment system for dam-break consequences and its corre-sponding indicator grading standards,based on grey system theory,fuzzy mathematics,and matter-ele-ment analysis theory,a grey-fuzzy matter-element analysis method applicable for prioritizing the conse-quences of dam-break events within dam groups was proposed.This method effectively integrated multi-dimensional evaluation indicators,including life loss,economic loss,environmental impact,and social im-pact.The severity levels of dam-break consequences across the dam group were classified through correla-tion degree analysis.Theoretical analysis and case study verification demonstrated that the proposed meth-od could provide a scientific basis for decision-making regarding the reinforcement priorities for dangerous reservoirs.
