| 摘 要： | 依据碳纤维增强混凝土(CFRC)的导电性，利用分段测电阻及红外热像法检测了CFRC试块承受不同载荷的损伤情况，与传统的应变片测量作了比较。结果表明：利用CFRC的功能特性检测损伤的方法要丰富得多，而且有效。

| Abstract: | Utilizing the conductivity of carbon fiber reinforced concrete (CFRC), the damage characteristic of CFRC specimen subjected to different levels of loading were detected by means of segmental resistance measurement and infrared thermograph, and were compared with that measured by conventional strain gauge. Obtained results revealed that this damage detection method exploiting the functional properties of CFRC is sensitive and effective. |
