摘　　要：以陕西神木采兔沟水库工程为实例,对探地雷达的工作原理及实际应用进行了介绍。结合采兔沟泄洪洞洞身的质量检测对具体的测线布置、探测方法及参数选择进行了阐述,在探测中,针对泄洪洞具体形状,在不同部位共布置了17条测线,经对检测结果分析,发现导流泄洪洞底板下方虽存在疏松区域,但不存在空洞,其他部位亦无大的缺陷,不影响安全运行。The working principle of Ground Penetrating Radar（GPR） and its application are introduced,and the Caitugou Reservoir in Shenmu,Shaanxi Province is taken as an example.The arrangement of survey lines,detection method and parameters selection are described.In the detection of the body of the spillway tunnel,17 survey lines are arranged in different parts of the tunnel according to its specific shape.The analysis of the detecting results show that there is a loosen area below the bottom plate of the spillway tunnel,however,cavities and defects are not found,so the safe operation will not be affected.
