摘要
地质雷达在检测公路路面脱空方面已经取得了非常好的效果,而对于脱空大小的定量计算问题已成为当前检测中最为迫切的问题。我们在广东省地质科学基金的资助下,通过脱空薄层理论分析,建立了路面脱空的实际模型,进行检测分析,从而得出了路面脱空的反射的振幅大小与其垂向大小成正比的结论,并建立了地质雷达检测路面脱空的定量计算公式。从而使地质雷达检测路面脱空的定量化得以完成,使脱空反射的快速准确追踪成为可能,有较强的实用价值。
The sensational results have been achieved in the applications of the GPR to detect the road surface vacancy. How to detect the exact height of the road surface vacancy is the most urgent issue. Under the financial assistance of the Guangdong Geology Funds, the model for the road surface vacancy is established through discussing the reflecting theory of GPR, and the detection and analysis are carried out. It is concluded that the relationship of the amplitude of the GPR reflection and the height of the road surface vacancy is the direct ration. The formula to determine the height of the road surface vacancy by using the ground penetrating radar is established, which is very practical to determine the height.
