摘　　要：本文在简要介绍探地雷达方法原理的基础上,详细分析了浙江某海塘堤脚沉井防冲结构及其相关介质的物理性质和空间分布特点,从而指出了堤脚淘空损伤雷达检测的基本可行性及复杂性.最后通过笔者实际参与的雷达检测试验和综合分析表明,采用雷达检测可指出淘空损伤现象存在的可能性及大致位置和范围,而难以断定损伤的性质及尺寸.On the basis of introducing methods and principle of ground penetrating radar （GPR）, the caisson scour protecting structure and the physical properties and spatial distribution character of related medium of one sea wall in Zhejiang province are analyzed in detail, it indicates the basic feasibility and complexity of detecting the hollow injury in the sea wall by means of GPR. And the practical experiment and comprehensive analysis demonstrate that the possibility, approximately position and range of the hollow injury can be detected, but it is difficult to judge its properties and size by means of GPR.
