【摘要】 探地雷达能检测公路路面的脱空,但一直以来,其对脱空大小的定量计算问题一直没有解决。为此,按公路路面的结构,建立了路面脱空的实际模型,进行检测试验分析,取得了一定成果:得出了路面脱空的反射振幅大小与其垂向大小成正比的结论,从而建立了探地雷达检测路面脱空的定量计算公式。该结论使探地雷达检测路面脱空能够定量化,使脱空反射的快速准确追踪成为可能,有较强的实用价值。更多还原

【Abstract】 It’s known to all that the GPR can be used to detect the road surface vacancy.Nevertheless,the detection of the exact height of the road surface vacancy remains an unsolved problem.With the financial support by the Guangdong Geological Funds,the authors established the models for the road surface vacancy in accordance with the road structure and made tests. It is concluded that there exist positive correction between the amplitude of the GPR reflection and the height of the road surface vacancy.The formula for determining the height of the road surface vacancy by the Ground Penetrating Radar was thus established.This means is very practical because with the formula the detection of the road surface vacancy by the Ground Penetrating Radar becomes very fast and the precision can be ensured.更多还原
