Abstract: Based on the physical characteristics of underwater riprap, as well as the research, application and development of water geophysical exploration technology, the current major detection methods such as high-density resistivity method, ground penetrating radar, water seismic reflection method and side-scan sonar were applied in quality inspection of the riprap protection of Yangtze river. Moreover, detection tests were carried out at 10 underwater riprap projects along the Yangtze river section in Anhui province. Then, comparison and analysis were made. The advantages, disadvantages and application ranges of these methods were proposed, for reference.

Key words: high-density resistivity method, ground penetrating radar, water seismic reflection method, side-scan sonar, riprap protection of Yangtze river
