基于灰色关联度和熵权法的水闸安全评价研究

Research on sluice gate safety evaluation based on grey relational analysis and entropy weight method

针对水闸运行安全问题,构建科学有效的水闸安全评价模型,通过建立综合评价指标体系,采取问卷调查法获取专家对指标重要性的评判;运用灰色关联系数法和熵权法相结合的方法计算各指标权重,以客观数据降低主观因素的影响,提高评价结果的准确性和可信度。选取团城湖调节池进水闸作为评价模型应用典型案例,证明方法的有效性和适用性。研究成果为水闸的安全评价提供了实践参考。

To address the operational safety issues of sluice gates,a scientific and effective safety evaluation model was constructed.By establishing a comprehensive evaluation index system and using a questionnaire survey method to gather expert judgments on the importance of each indicator,the model calculated the weights of the indicators by combining the grey relational analysis method and the entropy weight method.This approach used objective data to reduce the influence of subjective factors,thereby enhancing the accuracy and reliability of the evaluation results.The intake sluice gate of the Tuancheng Lake regulating pool was selected as a typical case study to demonstrate the effectiveness and applicability of the evaluation model.The research provides practical references for the safety evaluation of sluice gates.
