微波遥感在岩土工程中应用的基础实验研究

Basic experimental research of the microwave remote sensing applied in rock and soil engineering

由电磁辐射理论知道 ,物质的微波辐射是热能激发组成物质分子的转动态能级跃迁辐射出的电磁波。在等温过程加载的条件下 ,对岩石和混凝土进行了 2 cm、3cm、1 0 cm 3个波段以及水平和垂直两种极化状态的实验 ,得出岩石和混凝土的微波辐射能量随压力变化而变化的实验结果 ,实验了不同岩性岩石和不同强度混凝土共计 40个试件 ,无一例外。变化规律是 :在 2 cm和 1 0 cm波段微波辐射能量随压力增加而增加 ,在 3cm波段微波辐射能量随应力增加而减少。

In the theory of electromagnetic radiation, substance's microwave radiation is the electromagnetic wave radiated by the substance molecules during the energy level transition at rotational state which is excited by the heat energy.The article is about the experiments conducted to the rock and concrete on the isothermal loading condition.The experiments are conducted in three wave bands of 2cm,3cm,10cm and two polarized states of horizontal and vertical ones.The experiments prove that the microwave radiation energy of the rock and concrete changes with the pressure.About 40 rock and concrete test units of different lithologies and different strengths are tested in the experiments and there is no exception.The changing regulation:In the bands of 2cm and 10cm,microwave radiation energy increases with pressure increasing.In the 3cm band, microwave radiation energy decreases with pressure increasing.
