鉴于水工钢闸门的安全状态评价需要考虑闸门运行情况、腐蚀情况、强度、刚度、动态性能等多方面的因素,提出了基于层次分析法和模糊综合评价的水工钢闸门安全评估方法。首先构建了水工钢闸门评估体系层次结构,然后根据层次分析法定性和定量确定了各影响因素的权重,最后建立了模糊综合评价模型对某水利工程水工钢闸门的安全状态进行了全面评价,评价结果为二类等级,比较准确地反映了闸门的实际安全状态。
In view of the factors that affect the safety status of hydraulic steel gate, such as gate operation, corrosion, strength, stiffness and dynamic performance, etc., a safety assessment method for hydraulic steel gate based on AHP and fuzzy comprehensive evaluation is proposed. Firstly, the hierarchy of hydraulic steel gate evaluation system is constructed. Then the weight of each influencing factor is determined qualitatively and quantitatively according to AHP. Finally, a fuzzy comprehensive evaluation model is established to evaluate the safety status of hydraulic steel gate. , The results of the evaluation for the second level, more accurately reflect the actual state of the security gate.
