摘　　要：土质堤防自身具有空间范围广、材料均质性差等特点,特别是对于水毁复建段堤防,由于抢险填筑时间紧迫,在填筑材料、施工工艺上往往难以严格要求。因此,可能存在的隐患类型复杂多样,探测难度较大。本文介绍了利用地质雷达实现堤防隐患的快速、高效、无损探测的基本原理与实际工作方法,弥补了传统探测方法周期长、成本高、代表性差等不足之处,并结合某水毁复建段堤防探测实例验证了地质雷达方法的实用性。The earth dike itself has the characteristics of both wide range of space and poor material heterogeneity. Especially for flood damaged dike which has been urgently repaired, it is often difficult to meet materials filling and construction technology standard. Base on the above two poits, there may be a variety of types of potential hazards which will be difficult to detect. This paper introduced the basic principle and practical methods of georadar to find potential hazards in dike quickly, efficiently and without damage. It overcame the disadvantages of traditional methods such as long period, high cost, poor representation etc. Its practicability was proved by an example of some flood damaged dike.
