In order to detect the location of deteriorated elements of the civil engineering stucture like concrete, tile, brick and covered plate, a new radiation thermal test using an infrared radiomenter was undertaken. In this study, several incedent heat energy was inected to the surface of the tested element with external abd internal dlaws such as sun, lamp, hot gas, indirect radiation combustion. The transient radiation surface temperature above the flaws was displayd on the CRT of the infrared radiometer. A observed image of the radiation temperature image above the flaw shows the existance of the flaw.We manufactured a high temperature radiation heater which radiates the heat of 20 kw to the surface of the structural element with several flaws. The test piece was indirectly heated by the radiation heater. The abnormal temperature distribution above the flaw was observed by the infrared radiometer. It was succeeded to detect the underground buried project of 30 cm in depth embedded in the earth using the radiation heater.As the application study, the method was successfully applied to detect the ancient house, dwelling pit, crack and seperation of the concrete structure.

为了检测土木工程结构中损坏元素（如混凝土、瓷砖、砖和盖板）的位置，使用红外辐射计进行了新的辐射热测试。在这项研究中，几种入射热能通过太阳、灯光、热气体、间接辐射燃烧等外部和内部热力被注入到被测元件的表面。红外辐射计的CRT上显示缺陷上方的瞬态辐射表面温度。缺陷上方的辐射温度图像的观察图像显示了缺陷的存在。我们制造了一种高温辐射加热器，它将20千瓦的热量辐射到有多个缺陷的结构元件的表面。试验片由辐射加热器间接加热。通过红外辐射计观察到缺陷上方的异常温度分布。成功利用辐射加热器对埋入地下30cm深的埋地工程进行了检测。作为应用研究，该方法成功应用于古民居、坑坑、混凝土结构裂缝、离析等检测。
