为对水闸安全评价方法作进一步研究,首先建立安全评价指标体系;接着采用改进群组G1法和基尼系数赋权法计算指标权重,并通过理想点法进行权重融合;然后构建水闸安全性态评价云模型;最后,将评价结果与实际安全鉴定结论对比以佐证评价结果的准确性。利用该模型对水闸的总体安全性态作出评价,分析水闸评价分项存在的问题,并基于该模型评价结果对水闸安全性态作出预测,对水闸的运行管理和日常维护提出建议。通过实例计算发现评价结果与该水闸的安全鉴定结论一致。该模型给出了水闸与其各评价分项的安全等级,并通过MatLab生成云图,直观地反映了水闸评价结果。

A cloud model of evaluating the safety status of sluice was presented and applied in this paper. First of all, the safety evaluation index system was established; secondly, the weights were calculated using the improved Group-G1 method and Gini coefficient method, and the weights were combined by the ideal point method; the model was constructed and then applied to a case study; and finally, the evaluation result was compared with actual safety appraisal result in the purpose of verifying the correctness of the model. The model was adopted to analyze the problems in the sub-items of the sluice evaluation, predict the safety status of the sluice, and put forward suggestions for the operation management and daily maintenance of the sluice. The actual safety appraisal result was consistent with that of model computation. The model gave the safety grades of the sluice and its various evaluation sub-items, and generated cloud chart through MatLab to directly reflect the evaluation results of the sluice.
