| 摘 要： | 实验证明，当物质（体）受到应力作用时，应力能够引起物质（体）电磁辐射能量发生改变．遥感器接收到的电磁辐射能量是由受载物体自身温度和应力共同引起的总辐射能量（观测值）组成．如何将二者定量地分离开，进而反演介质所处的温度状态和应力状态，在地震预测预报、大型岩土工程稳定性监测中, 是一个具有实际意义的问题．本文详细论述了如何采用多波段遥感观测，通过数学手段将二者分离并反演应力的方法, 并列举算例加以证实．

| Abstract: | It has been proved through experiments that the stress will cause a variation in the electromagnetic radiation energy of a substance loaded by force. This moment, the electromagnetic radiation energy (observation value) received by the remote sensor is triggered not only by the substance temperature and also by the stress. Separating quantitatively these two kinds of electromagnetic radiation energy and then inversing the actual temperature state and stress state of a medium is a matter with practical significance in earthquake prediction and stability monitoring for the large scale geotechnical engineering. In this paper the principle and the mathematical method of separation and inversion are discussed in detail. A calculation example is listed by using observation data of multiband remote sensing, which proves that the method is correct. |
