摘要
介绍了探地雷达技术的发展现状及其在地下介质中传播的基本原理。并结合工程实际,利用探地雷达技术对宜万铁路W 7段5号墩进行岩溶探测,参考岩溶雷达图像的特征,通过合理布置测线和认真分析雷达图像圈定了该墩区域的岩溶位置。实践证明,应用探地雷达探测隐伏岩溶是一种快速、高效、经济、可靠的物探方法。
The development of ground-penetrating radar and its basic principle of GPR wave propagating underground is introduced. In virtue of actual project, the hidden karst under the fifth pier of W7 part in Yi-wan railway is detected successfully by assigning survey lines reasonably, considering the characteristics of GPR picture and analyzing the GPR picture seriously. It is proved by practice that the method of GPR is a rapid, efficient, economic and reliable method to detect the hidden karst.
