METHOD AND SYSTEM FOR MONITORING CIVIL ENGINEERING CONSTRUCTION
PROBLEM TO BE SOLVED: To provide a method for detecting a potential structural defect linked to corrosion and/or ageing and the like of a metal reinforcing material in a civil engineering construction.SOLUTION: A method for monitoring a civil engineering construction is provided, the civil engineering construction comprising a first metal reinforcement 1 contributing to the mechanical strength of the construction, and a reference conductor element 2, these being separated by dielectric material 3 and having first ends 11, 21 respectively that are electrically accessible, the method comprising: A--injecting an incident electrical signal which is applied differentially between the first ends of the first reinforcement and of the reference conductor element, B--collecting reflected signals returning along the conductors in return, C--analysing the reflected signals and comparing them against reference signals to deduce from the result thereof any potential structural defect in the first reinforcement.SELECTED DRAWING: Figure 2
【課題】土木建造物における金属補強材の腐食および／または経年劣化等につながる潜在的な構造的欠陥を検出する方法を提供する。【解決手段】土木建造物の機械的強度を助長する第１の金属補強材１と、基準導体要素２とを含み、これらは誘電体３によって分離されており、各々電気的に利用可能な第１の端部１１、２１を有しており、上記方法は、Ａ‐第１の補強材の第１の端部と、基準導体要素の第１の端部との間の差として加えられる入射電気信号を注入する工程と、Ｂ‐それと引き換えに導体に沿って復帰する反射信号を収集する工程と、Ｃ‐反射信号を分析し、それらを基準信号と比較し、その結果から、第１の補強材における各潜在的な構造的欠陥を推定する工程と、を有する。【選択図】図２
