DETERIORATION DETERMINATION METHOD AND DETERIORATION DETERMINATION DEVICE
To determine a deterioration state of an underground metallic structure, and facilitate determination of renewal of an underground metallic structure.SOLUTION: A measurement part 11 measures a residual thickness and a surface roughness index value about whole part or a part of a metal member forming a metallic structure which is collected after progress of corrosion due to being subjected to actual use for a long term, a simulation shape creation part 12 creates a simulation shape plane model based on a measurement result of the measurement part 11. A whole simulation shape creation part 13 creates a whole simulation shape model when the metal structure becomes in a certain corrosion state based on the simulation shape plane model. A strength calculation part 14 calculates strength indicated when the metal structure becomes in a certain corrosion state based on the whole simulation shape model. A deterioration determination part 15 compares the strength calculated by the strength calculation part 14 with strength indicated when a metal structure stored in a storage part 16 is new, for determining a deterioration state.SELECTED DRAWING: Figure 1
【課題】地中金属構造物の劣化状態を判定し、地中金属構造物の更改の判断を容易にする。【解決手段】測定部１１が長年実使用に供されて腐食が進行した後に回収した金属構造物を構成する金属部材の全部または一部について残存肉厚と表面粗さ指標値とを測定し、模擬形状生成部１２が測定部１１の測定結果に基づいて模擬形状平面モデルを生成し、全体模擬形状生成部１３が模擬形状平面モデルから金属構造物がある腐食状態になった場合の全体模擬形状モデルを生成し、強度算出部１４が全体模擬形状モデルを基に、金属構造物がある腐食状態になった場合に示す強度を計算し、劣化判定部１５が強度算出部１４の算出した強度と記憶部１６に記憶した金属構造物が新品の場合に示す強度とを比較して劣化状態を判定する。【選択図】図１
