摘要:

摘要:在进行水工钢闸门安全综合评估时,构建了结构强度、过水能力、挡水能力、服役指标4个指标作为其评估指标体系,并通过多专家应用层次分析法确定指标权重,且为避免因专家的主观因素造成的权重差异,引 入灰色关联分析法避免多专家意见不统一造成的权重分配错误,使评估更加科学合理。针对水工钢闸门安全评价指标的不确定性,引 入集对分析法,将评估指标与评估标准构建成1个集对,建立了水工钢闸门安全综合评估的集对分析模型,实例计算结果验。

Abstract:

Abstract:When making a formal safety assessment of hydraulic steel gate, four indicators: structural strength,discharge capacity, water retaining capacity and service indicator are constructed as the assessment indicators system, and the weight of indicators is confirmed by experts using the analytic hierarchy process. Moreover, the grey relational analysis method is introduced to avoid the weight differences which are caused by subjective factors of experts and make the assessment more scientific and reasonable. For the uncertainty of formal safety assessment indicators of hydraulic steel gate, the set pair analysis is introduced, and a set pair analysis model for formal safety assessment of hydraulic steel gate is built by constructing a set pair of assessment indicators and assessment criteria. The calculation result of example verifies the effectiveness of set pair analysis forthe formal safety assessment of hydraulic steel gate.
