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。
Geological radars have achieved very good results in the detection of road surface emptying. However, the quantitative calculation of void size has become the most urgent problem in current testing. With the help of Guangdong Provincial Geological Science Fund, we established the actual model of pavement void through the analysis of void-free thin-layer theory and carried out testing and analysis. It is concluded that the magnitude of the reflection of pavement emptying is proportional to the vertical size The conclusion is reached that the quantitative calculation formula for detecting the emptying of pavement by GPR is established. Therefore, the quantification of the void detection by the ground radar can be completed, which makes the rapid and accurate tracking of the void reflection possible and has a strong practical value.
