REINFORCED CONCRETE STRUCTURE EVALUATION EQUIPMENT, METHOD, AND PROGRAM
To quantitatively evaluate the degree of deterioration and damage inside a reinforced concrete structure.SOLUTION: An acquisition unit 12 acquires a reflected wave intensity image that shows the intensity of reflected waves of electromagnetic waves radiated from a surface toward the inside of a reinforced concrete structure at each position on the surface of the reinforced concrete structure by pixel values of the pixel corresponding to each position: a setting unit 14 sets a range of an evaluation target in the reflected wave intensity image acquired by the acquisition unit 12: a calculation unit 16 calculates a statistical index of a type according to the range set by the setting unit 14 for the pixel value in the reflected wave intensity image: and an evaluation unit 18 evaluates the degree of deterioration and damage of the reinforced concrete structure using a value calculated by the calculation unit 16.SELECTED DRAWING: Figure 6
【課題】鉄筋コンクリート構造物内部の劣化損傷具合を定量的に評価する。【解決手段】取得部１２が、鉄筋コンクリート構造物の表面の各位置において、表面から鉄筋コンクリート構造物の内部方向へ照射した電磁波の反射波の強度を、各位置に対応する画素の画素値で表した反射波強度画像を取得し、設定部１４が、取得部１２により取得された反射波強度画像において、評価対象の範囲を設定し、算出部１６が、反射波強度画像における画素値について、設定部１４により設定された範囲に応じた種類の統計的指標を算出し、評価部１８が、算出部１６により算出された値を用いて、鉄筋コンクリート構造物の劣化損傷具合を評価する。【選択図】図６
