本文提出了一种水闸老化的模糊集合论评估方法。该方法是：首先把水闸分解成部件，然后就每个部件的安全性、适用性和耐久性及其所属的若干单因素评估指标，计算出部件老化的综合隶属度，再用系统综合的方法评出整个水闸的老化级别。本方法的绝大多数数据都来源于实际检测资料，并以现行标准和规范作为准绳进行评估，因而得出的评估结构比较准确。 This paper presents a method of fuzzy set theory evaluation of sluice aging. The method is as follows: firstly, the sluice is decomposed into parts, and then the comprehensive membership degree of parts aging is calculated based on the safety, suitability and durability of each part and the evaluation indexes of several single factors which belong to them, and then the method of system synthesis Evaluate the age of the entire sluice. The vast majority of data in this method are derived from the actual testing data and are evaluated based on the current standards and norms. As a result, the evaluation structure obtained is more accurate.
