摘　　要：对现役水工钢闸门安全状态评估时通常需要综合考虑多个方面评估指标的影响,这些指标中有定性指标和定量指标两类,对这些指标进行综合评估是一个充满不确定性和模糊性的问题。基于此,将直觉模糊层次法和云模型方法相结合来评估闸门的安全状态。首先,基于层次分析的思想,构建了水工钢闸门的评估指标体系,再依据直觉模糊的理论,邀请专家对每个评估指标进行比较,建立直觉模糊判断矩阵,综合分析并确定各项指标的权重。再采用云模型的方法,结合工程实例,建立各个指标的诊断云图,最终得到该闸门的诊断云图,并与状态云图进行比较,得出该闸门的安全状态,与实际情况相比较,该方法的结果是准确且直观的。When evaluating the safety status of hydraulic steel gate in service,it is usually necessary to comprehensively consider the influ⁃ence of evaluation indexes from many aspects,among which there are qualitative and quantitative indexes,which is an issue of uncertainty and fuzziness.Based on this,this paper combined the intuitionistic fuzzy hierarchy method and cloud model method to evaluate the safety state of the gate.Firstly,this paper built the evaluation structure system of hydraulic steel gate based on the idea of hierarchy method,and then invited experts to evaluate and compare the indicators on the basis of intuitionistic fuzzy theory,established the judgment matrix and comprehensively analyzed the weight of each indicator.To adopt the method of cloud model,combining with engineering example,set up the index of diagnosis of cloud,the diagnosis of synthesis of various cloud chart,finally got the diagnosis cloud gate test result and comparing with state chart,finally it was concluded that the gate security status.Comparing with the actual situation,the results of this method are accu⁃rate and intuitive.
