| 摘 要： | 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。

| Abstract: | The loading experiments of microwave and infrared radiation in concrete are made in labratory. It is discovered that the enersy of microwave and infrared radiation in concrete is changed remarkably with the stress state in it, and it is also discovered that various rupture precursors of microwave and infrared radiation appeared before the failure of concrete sample. The discovery of these physical phenomena shows that the microwave and the infrared remote sensing can be used to measure the stress and stress field distribution in concrete engineerings and can monitor and predict the danger or the failure of concrete engineerings caused by stress concentration. |
