摘要
以含有缺陷的混凝土结构试件为研究对象,运用传热学理论,对热流在试件内部的传递过程进行了仿真分析,获得了试件表面的温度信号。结果表明,缺陷处与完好材料处对应试件表面温度存在着明显差异,红外热成像无损检测技术可用于实现对混凝土内部缺陷的检测。
Concrete column with inner defect is the research target, the simulation about the transmission process of heat flow in the concrete specimen is carried out with the thermal transmission theory, the temperature signal on the upper surface of the concrete specimen is achieved. The results show that, there exists obvious distinguish between the （tefects and the specimen body, the thermal infrared imaging nondestructive examination can be used to detect the ironer defect of concrete column.
