探地雷达检测公路面层厚度的准确性研究

Research on Accuracy of Highway Surface Thickness Tested by Ground Penetrating Radar

在简述探地雷达基本原理和工作方法的基础上,对用探地雷达检测道路面层厚度的可靠性、准确性进行了分析,并通过试验予以验证。试验结果表明:探地雷达对于每一点厚度测量比较精确,而对于某一段的厚度测量则是非常精确,说明探地雷达完全具备替代现行钻孔取芯的条件。

On the basis of the brief introduction of the basic principles and work methods of radar, the reliability and accuracy of using the ground penetrating radar to test the thickness of highway surface is analyzed and verified by tests. The tests show that the ground penetrating radar can test each segment of the highway very accurately, but only relatively accurate when it tests each spot of the highway. The tests prove that the ground penetrating radar is eligible to replace the present method of drilling to get core sample.
