探地雷达技术是如今适应快速、准确、无损地探测地下障碍物而迅速发展的电磁技术。文中介绍了探地雷达的工作原理及工作方式，并通过结合工程实例来探讨探地雷达在地下管线探测中的广泛应用。

Ground penetrating radar (GPR), a new electrom ag netic method, has been quickly developed to meet the requirement for probing the underground obstacle fast, precisely and undamaged. Theory and method of ground penetrating radar are introduced. It is discussed in this paper that ground pen etrating radar is widely used in detecting of underground pipelines through some engineering examples.
