摘要
在等温过程加载条件下 ,得出混凝土等固体物质的微波幅射能量随压力变化的实验结果 .实验证明了机械能可直接激发固体物质分子的转动态能级发生跃迁 ,不需要经历生热的中间物理过程 .这一物理现象把应力同微波辐射能量从物理上直接联系了起来 ,为无源微波遥感用于测量大型混凝土工程应力场分布、演变 ,用于岩土工程稳定性监测和失稳预测 ,提供了实验依据 ,奠定了物理基础
Under the experimental condition of loading in isothermal process, the microwave radiation energy of solid matters like concrete varied with the change of pressure. Experiments were carried out considering two polarized states (horizontal and vertical) of 3 wave bands including 2cm, 3cm, and 10cm. The experiments demonstrated that mechanical energy can directly excite rotation state energy level jump of solid matters (rocks and concrete, etc.) molecules without need of intermediate physical process of heat generating. This phenomenon directly connects stress with microwave radiation energy physically. This paper puts forward experimental basis and lays physical foundation for the remote measurement of stressfield distribution and evolvement of large concrete engineering by passive microwave remote sensing, and for rock engineering’s stability monitoring and stability failure predicting.
