Abstract:	目前國內、外對於腐蝕鋼筋混凝土構件非破壞性檢測大多以電化學之腐蝕電位方法來進行檢測及研判腐蝕程度，較少以透地雷達電磁波波傳行為與反射訊號來進行鋼筋腐蝕程度探討。而本研究針對不同混凝土保護層深度的鋼筋進行加速腐蝕試驗後，藉由透地雷達之電磁波反射訊號來探討混凝土內不同腐蝕程度鋼筋之反射訊號與電壓差異及不同電性參數之反射係數與反射功率大小，並與電化學方式(腐蝕電位與電流)進行定性分析比較，藉此暸解電磁波反射訊號與腐蝕電位與電流之物理關係。由此建立透地雷達評估鋼筋腐蝕行為判定參考與評估依據。 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
