%X The detection of hidden dangers of embankment plays an important role in guaranteeing the safe operation of levee project. There are various geophysical detection methods for hidden dangers, each having their own advantages and applicability. It is difficult to solve all kinds of hidden danger detection problems by only one method. According to the geophysical parameters such as conductivity and dielectric property, the commonly used geophysical detection methods for hidden dangers of embankment are summarized. Moreover, through laboratory geotechnical tests, the correlation between resistivity, dielectric constant, moisture content and compactness of embankment soil is established, which provides an experimental and theoretical basis for improving the accuracy of geophysical interpretation. With the Yangtze River embankment  project as a case study, the selection of geophysical detection methods, the arrangement of survey lines, the geological interpretation and detection effects are analyzed. It is verified that the comprehensive geophysical detection method can improve the detection precision of hidden dangers and achieve the purpose of accuracy, efficiency and economy.
