Abstract: The technique of ground penetrating radar (GPR) is a high-tech technique for examination, which has a lot of advantages such as high degree of accuracy, non-stop operation, non-destructive, economical, rapid survey, audio visual and so on. We can identify abnormalities in object interior with GPR by transmitting electromagnetic waves of high frequency to object interior and receiving the backward waves.When applying the technique of GPR to water-power engineering, the author detected the interface between the overburden layer and the fracture zone of the earth slide in some hydroelectric stations and some of the solution cavities in the reservoir area of some pumped-storage power stations.

摘要： 地质雷达技术是一种高精度、连续无损、经济快速、图像直观的高科技检测技术。它是通过地质雷达向物体内部发射高频电磁波并接收相应的反射波束判断物体内部异常情况，作者将地质雷达技术应用到水电工程中，探测出某水电站滑坡体覆盖层与破碎带的分界面和某抽水蓄能电站库区溶洞，解决了实际工程问题。
