Abstract：In view of the subjectivity defects of judgment matrix expert judgment for the traditional analytic hi-erarchy process ( AHP) , a new comprehensive evaluation method of the state for bridge structures considering the fuzziness judge is presented in the paper.On the basis of the basic fuzzy theory , triangular fuzzy numbers are given to the judge instead of the traditional scaling factor weight calculation method , the processes and im-plementation steps of comprehensive fuzzy AHP for bridge state evaluation method were built .Using the pro-posed method to evaluate a reinforced concrete bridge structure state based on the results of sensing data , the re-sult showed that the proposed method not only can reflect the uncertainty and fuzziness for bridge sate evalua -tion, but also can fully consider the major influence factors and reflect the comprehensive status of bridges .
