摘要
以层次分析法为基础,应用模糊系统理论建立了一种桥梁结构耐久性评定的模糊综合评定法。该方法在桥梁结构耐久性多层次综合评定模型的基础上建立了各级评价因素对各耐久性等级的隶属函数,考虑评价因素对目标评定值的权重,由最大隶属原则,得出待评定桥梁结构的耐久性等级,以此推断出该桥梁加固前与加固后的耐久性使用寿命,具有一定的实用性。
It is set up a fuzzy overall assessment method of concrete bridge durability applying fuzzy theory; based on the muhiplayer analysis, this method builds functions that describe the subjection degree of all factors to all grades of durability. Then this method takes the weight of all factors into account and applies the most subjection criterion to get the grade of durability of a concrete bridge, and with this prediction the useful life of durability of the concrete bridge before and after strengthening also can make a quantitatively, so the method is practical.
