The Comprehensive Assessment of Dam Risk Consequences Caused by The Dam Failure Based on The Set Pair Analysis

The comprehensive assessment of dam risk consequences caused by the dam failure is difficult because of the uncertainty, inter related and the non unification of the risk consequences. For this problem, combining with the existing laws and regulations of dam failure accidents classification rules, this paper propose an dam risk comprehensive evaluation modelmodel based on set pair analysis. This modle can discribe the degree of convergence of the consequences and the accident risk level from the same, different, opposite three aspects. According to the Maximum set pair potential theory, the model can get the dam risk consequences comprehensive evaluation level and the sorting. The evaluation model was applied to 5 dams comprehensive evaluation of jiangxi province. The evaluation result was compared with another resulet based on the attribute interval computation model. Results show that the set pair analysis evaluation model process is simple, and has less computation, and the evaluation result is reasonable, objective and comprehensive, clear. This model provides a new way for comprehensive evaluation for dam risk consequences.
