基于联系数的水闸安全综合评价物元模型与实现方法

针对水闸工程安全评价指标间存在的不相容性及关联性等问题,将联系数原理引入物元理论,详细介绍了基于四元联系数的水闸安全综合评价物元模型的基本原理以及实现过程,提出了一种基于线性插值原理的水闸安全评价单指标联系数的计算方法。利用该评价模型,从同、异、反3个方面综合刻画某水闸构筑物的安全状况,对其安全等级进行鉴定,并基于联系势原理评估该水闸运行状态的发展趋向,在此基础上,对该水闸的运行维护及管理工作提出了指导性建议。计算实例表明,相比于传统物元分析方法,该评价模型实现过程简单,评价结果可靠,为类似工程的安全评估提供了新思路。

Matter-element Model of Sluice Safety AssessmentBased on Connection Number

In view of the incompatibility and relevance among indexes of safety evaluation for sluice project, four-tuple connection number is incorporated into matter-element model to comprehensively evaluate sluice safety. The basic principle and modeling method are expounded. A method for calculating the connection number of single index based on linear interpolation principle is proposed. Using the evaluation model, the safety status of a sluice structure is depicted comprehensively from three aspects including similarity, difference and inverse. The safety level is appraised and the development trend of the sluice project is evaluated based on the connection trend theory. On this basis, guiding suggestions are put forward for the operation, maintenance and management of the sluice. Computational example manifests that the evaluation model is simpler and more reliable than traditional matter-element analysis method.
