基于模糊推理规则的桥梁结构状态评估

Bridges Condition Assessment Based on Fuzzy Inference Rules

为了给桥梁养护管理部门提供决策依据,在桥梁结构状态评估中引入模糊推理的思路,根据模糊规则,生成相应的模糊规则库,采用Sigmoid型模糊隶属度函数对底层输入指标模糊化,然后根据模糊规则进行模糊推理,从而对既有桥梁结构的状态做出综合评估。结果表明,该方法避免了权重计算,为桥梁状态评估提供了一种切实可行的方法。

In order to provide a decision to the bridge management department, fuzzy inference was introduced to bridge condition assessment, Based on the fuzzy rule, the knowledge base of fuzzy rules were gained, and sigmoid membership function was used to calculate the grade of the input items, then the fuzzy inference based on the fuzzy rules were implemented and a comprehensive assessment of bridge condition was given. The recognition result showed that the proposed method avoided the calculation of weight and provided a feasibility method for bridge condition assessment.
