To analyze nondestructive inspection data by artificial intelligence and thereby discriminate the degradation state of a prestressed concrete (PC) steel with high accuracy.SOLUTION: The present invention is characterized by causing a computer to execute an association degree acquisition step for previously acquiring the degree of association in three or more levels of the inspection data of past nondestructive inspection of a PC steel 72 with the discrimination result of degradation state of the PC steel 72 with regard to the inspection data; an input step in which is inputted the inspection data obtained by conducting nondestructive inspection on a PC structure 7 to be newly discriminated for degradation state in which the PC steel 72 is buried; and a discrimination step for referring to the degree of association acquired in the association degree acquisition step and discriminating the degradation state of the PC steel 72 on the basis of the information inputted in the input step.SELECTED DRAWING: Figure 1 【課題】非破壊検査データを人工知能により解析することで、そのＰＣ鋼材の劣化状況の判別を高精度に行う。【解決手段】ＰＣ鋼材７２に対する過去の非破壊検査の検査データと、当該検査データに対するＰＣ鋼材７２の劣化状況の判別結果との３段階以上の連関度を予め取得する連関度取得ステップと、新たに劣化状況を判別するＰＣ鋼材７２が埋設されたＰＣ構造物７に対して上記非破壊検査を行うことにより得られた検査データが入力される入力ステップと、上記連関度取得ステップにおいて取得した連関度を参照し、上記入力ステップにおいて入力された情報に基づき、ＰＣ鋼材７２の劣化状況を判別する判別ステップとをコンピュータに実行させることを特徴とする。【選択図】図１
