对混凝土的微波辐射和红外辐射在实验室进行了加载实验，发现混凝土的微波辐射能量和红外辐射能量随混凝土应力状态变化而显著变化，且混凝土试件临破裂前，微波辐射和红外辐射出现多种破裂前兆异常。这表明微波遥感和红外遥感可用于混凝土工程应力和应力场分布测量，并可用于混凝土工程因应力集中造成工程可能发生危险或遭到破坏时的监测和预报。
Experiments on microwave radiation and infrared radiation of concrete were carried out in the laboratory. It was found that the microwave radiation energy and infrared radiation energy of concrete significantly change with the change of the stress state of concrete, and before the concrete specimen fractures, there are many microwave radiation and infrared radiation. This type of rupture precursor is abnormal. This shows that microwave remote sensing and infrared remote sensing can be used to measure the distribution of stress and stress fields in concrete engineering, and can be used for monitoring and forecasting of concrete projects that may cause danger or damage to the project due to stress concentration.
