CT扫描技术在混凝土结构检测中的应用

Application of CT scanning technology in detection of concrete structure

为了解CT扫描技术在工程检测应用中的可行性及优越性,特别选取预制典型裂缝、疲劳加载、锈胀裂缝及现场混凝土构件,对其进行CT扫描室内试验,获得构件典型病害CT图像。试验分析表明:CT扫描成像能直观体现混凝土内部的缺陷和破损情况,并能对缺陷和破损进行定量分析,可见该检测技术应用效果良好。随着CT扫描仪器的发展,便携式CT将成为可能,CT扫描技术在混凝土结构检测中必将占有重要的地位。

To explore the feasibility and superiority of CT scanning technology in engineering detection, we make CT scanning for the typical fracture and fatigue loading, corrosive cracks and site concrete member and obtain the CT image for typical disease of components. The experimental analysis shows that a CT scan imaging can visualize the inside concrete defects and damages and carries on the quantitative analysis. With the development of CT scanners, portable CT will appear in the future, and CT scanning technology will play an important role in the concrete structure detection.
