地质雷达探测技术在路基工程中的应用

Application of geological radar technology in detecting subgrade engineering

介绍了地质雷达探测公路路基的基本原理及雷达探测相关参数的选择等问题。通过对某国道拓宽改造工程一定范围内的路基进行探测,采用专业雷达处理分析系统对雷达信号进行了处理分析,得到公路路基一定范围内的地质雷达图像并对图像结果进行了详细分析,定性的确定了空洞区的存在与否,为后续整治工程隐患提供了一定的参考依据。

This article presents fundamental principle of using geological radar technology to detect the high-way subgrade and the selection of correlative parameters in radar detecting. A certain range of the roadbed of some widening reconstruction projects is detected. Radar signal is analyzed by professional radar processing and analysis system. And geological radar images of subgrade are got. And these images will be detailed ana- lyzed. So the cavity area will be qualitatively confirmed. The study would provide some useful information for follow up regulation project.
