摘　　要：在等温过程加载条件下 ,实验得到混凝土的红外辐射能量随压力变化而显著变化的结果 ,这个变化与温度无关 ,完全由压力引起 ,不需要经历生热中间物理过程。这一物理现象在国内外未见报道 ,为混凝土工程应力测量提出了新原理、新方法和新技术 ;为红外遥感测量应力和温度异常用于工程稳定性监测和失稳预测等领域 ,提供了实验依据 ,奠定了物理基础 。Under the loading condition of isothermal process, the experimental result shows that the infrared radiation energy of concrete is varied markedly with the change of pressure. This change is caused completely by pressure, and independent of temperature with no intermediate physical process of heat generating. This physical phenomenon has not been presented before. The new principle, method and technology for the stress measurement in concrete engineering are put forward. The experimental basis and the physical foundation are offered for the measurement of stress and temperature abnormality with the infrared remote sensing, and for the engineering stability monitoring and unstability prediction, etc.
