摘　　要：现役混凝土结构内钢筋腐蚀速度的实时监测是其健康监测的一个重要内容。对当前混凝土内钢筋腐蚀速度的主要测试方法进行了介绍和比较,设计了一种用于现役混凝土结构内钢筋腐蚀速度监测的"宏电池腐蚀电偶探头(Macro-cellprobe)",并在实验室内和现场结构进行了实验验证。结果表明,该方法具有构造简单、测试方便、数据较为可靠等特点。The real time monitor of the corrosion rate of the steel bar in existing concrete structures is one of the important contents of its healthy monitoring. In this paper some main testing methods of the corrosion rate of steel bar in concrete were introduced and compared, and one method of macro-cell probe aimed at monitoring the corrosion rate of steel bar in existing concrete structures was put forward. Through the experiment results in laboratory and the validation of structures in the field, this method is indicated that has characteristics of simple constitution, convenient operation and reliable results etc.
