结合钱塘江古海塘工程实例，通过两种探地雷达的现场探测，以及对检测过程和结果的详细阐释，介绍了地质雷达探测技术在水利工程的古海塘隐患探测中的应用。地质雷达检测结果未发现严重隐患，海塘目前整体稳定，测试结果为古海塘典型区段结构的检测与评估提供了重要依据。%The ground penetrating radar (GPR) ,a kind of geological detection technology ,is widely used in various engineering detection and prediction due to its high efficiency ,high resolution ,and non‐detective .The ancient seawall along the bank of Hangzhou Bay ,which plays an important role in minimizing hazards ,has existed for hundreds of years .This work focuses on the application in the detective engineering of the ancient seawall of two different GPR instruments .And no serious problems are found ,which indicates the overall stability of the ancient seawall .The results provide an important basis for the detection and assessment of the typical structure section of the ancient seawall .
