STEEL PLATE DECK BRIDGE EVALUATION APPARATUS, STEEL PLATE DECK BRIDGE EVALUATION METHOD, AND PROGRAM
To provide a steel plate deck bridge evaluation apparatus which can quantitatively evaluate an inside of a steel plate deck bridge for damage and deterioration.SOLUTION: A steel plate deck bridge evaluation apparatus 10 comprises: an acquisition unit 100 which acquires reflection response data on reflection response of an electromagnetic wave radiated from a surface of a plate deck in a depth direction of the plate deck; a removal unit 101 which removes a first frequency component obtained by the electromagnetic wave being reflected by the surface 96 of the plate deck and a second frequency component obtained by the electromagnetic wave being reflected by a steel plate deck 98 from a frequency distribution of the reflection response represented by the reflection response data acquired by the acquisition unit 100; and an evaluation unit 102 which evaluates the plate deck for damage and deterioration using a measurement peak value, which is a peak value of a level of a frequency component equal to or more than a certain frequency, in the frequency distribution of the reflection response with the first frequency component and the second frequency component removed therefrom by the removal unit 101.SELECTED DRAWING: Figure 6
【課題】鋼床版橋内部の損傷劣化を定量的に評価することができる鋼床版橋評価装置を提供する。【解決手段】鋼床版橋評価装置１０は、床版の表面から床版の深さ方向へ照射した電磁波の反射応答に関する反射応答データを取得する取得部１００と、取得部１００により取得された反射応答データが表す反射応答の周波数分布から、床版の表面９６で電磁波が反射して得られた第１周波数成分と鋼床版９８で電磁波が反射して得られた第２周波数成分とを除去する除去部１０１と、除去部１０１により第１周波数成分及び第２周波数成分が除去された反射応答の周波数分布における、特定周波数以上の周波数成分のレベルのピーク値である測定ピーク値を用いて、床版の損傷劣化を評価する評価部１０２とを有する。【選択図】図６
