桥梁结构健康评价的指标体系通常比较复杂，专家评分或层次分析法获取因素权重的方法过程繁琐且主观性强。针对该问题，提出一种将粗糙集与层次分析法相结合来获取因素权重的方法，并基于该方法建立了桥梁结构健康多级模糊综合评价模型。利用该评价模型，对实测的桥梁结构状态数据进行分析与评价。实验结果表明，该模型能够对桥梁结构健康状态进行较为准确的评价，评价准确率优于层次分析法。

In a general way, the index system of bridge structure health evaluation is very complex, so the method of expert grading or analytic hierarchy process is tedious and has strong subjective. Aiming at these problems, this paper puts forward a method which combines rough set with analytic hierarchy process theory to obtain factor weights, and based on this method, bridge structure health multi-level fuzzy comprehensive evaluation model is established. The model is used to analyze and evalu-ate bridge structure status data. The experimental results show that this model can evaluate bridge structure health accurately, and evaluation accuracy rate of this method is significantly higher than that of analytic hierarchy process.
