Abstract: Due to the complexity of correlation among the reinforcement alternatives and dangerous types, disease degree, risk size, economic requirements, environmental requirements, sustainable development and many other factors, it is generally difficult to determine the best reinforcement alternative. In this paper, the decision-making of reinforcement alternatives based on dangerous types, disease degree and dam risk is presented by using the grey correlation analysis model. It is proved that the decision-making of reinforcement alternatives for the dangerous reservoirs based on the proposed approach could be obtained objectively and scientifically.

Key words: dangerous reservoir, reinforcement alternatives, correlation analysis, decision-making
