探地雷达是近几十年来被广泛应用的一种浅层地球物理无损探测技术。在铁路公路、隧道工程、工程建筑、水电工程等领域都有广泛应用。该文重点介绍了探地雷达对隧道衬砌可能存在的施工缺陷进行检测的方法,通过对所获得的雷达图像特征的分析,确定出了隧道衬砌工程中的缺陷和缺陷位置,经后期钻孔验证雷达探测是正确的。目前,探地雷达已经成为隧道工程质量检测中一种必不可少的有效的消除和防止工程隐患的手段。
Ground penetrating radar is a shallow geophysical nondestructive detection technique widely used in recent decades. In the railway, tunnel engineering, engineering construction, hydropower engineering and other fields have a wide range of applications. This article focuses on the detection of ground penetrating radar tunnel lining possible defects in the construction method of inspection, obtained by the radar image features to determine the tunnel lining engineering defects and defects in the position after the late drilling verification Radar detection is correct. At present, GPR has become an indispensable and effective means to eliminate and prevent hidden dangers in tunnel engineering quality inspection.
