Under the condition of isothermal loading, the experimental results of the microwave energy radiated by the solid material such as concrete with pressure were obtained.The experimental results show that the mechanical energy directly excites the transition of the energy level of the solid material molecules, and does not need to go through the middle of heat generation Physical process This physical phenomenon directly relates the stress to the energy of microwave radiation physically, and is used for measuring the stress field distribution and evolution of large-scale concrete engineering by passive microwave remote sensing. It is used for geotechnical stability monitoring and instability prediction , Provided the experimental basis, laid the physical foundation
