探地雷达检测高速公路隐伏空洞方法研究

Study on the Method of Detecting the Hidden Hole of the Expressway by Ground Penetrating Radar

介绍了常见的地面及地下的干扰电磁波特征,分析了涵洞、管道、松散路基、深部散射等电磁波反射特征。通过检测和实践,研究了隐伏空洞和脱空的电磁波反射规律,能够在诸多干扰电磁异常中准确判断隐伏空洞,可为高速公路安全运营、维护和空洞治理提供更加科学、准确基础资料。

This paper introduces the common characteristics of ground and underground electromagnetic waves, and analyzes the reflection characteristics of culverts, pipelines, loose subgrade and deep scattering. Through testing and practice, this paper studies the electromagnetic wave reflection law of hidden void and void, and can accurately judge hidden void in many interference electromagnetic anomalies, which can provide more scientific and accurate basic data for safe operation, maintenance and void management of expressway.
