Abstract:	透地雷達應用在鋼筋混凝土構件檢測已十分的普遍，而一般鋼筋混凝土構件中鋼筋的腐蝕大都以電化學的方式進行檢測，而本研究針對不同混凝土保護層厚度之鋼筋試體，進行加速腐蝕試驗，並應用透地雷達技術進行掃瞄，將透地雷達剖面圖進行數位化影像編碼運算，探討混凝土中內含不同腐蝕程度於不同保護層深度之鋼筋編碼值的差異及不同電性參數之電磁波波傳反射行為。本研究探討鋼筋腐蝕電位大小與電磁波反射電壓之關係，結果顯示透地雷達電磁波之反射電壓值可合理的定量預測鋼筋腐蝕程度嚴重與否，相較於鋼筋腐蝕電位量測，應用透地雷達電磁波檢測鋼筋之腐 Ground penetrating radar (GPR) has been widely used in the measurement of the structural steel within concrete at the time being. However, deep enough studies about its application in measurement of degree of corrosion of structural steel within concrete
