Abstract: Throughout a case history, the basic theory of the electromagnetic imaging technique, field applications, and the key aspects of this technology are presented. The application indicates that this method can detect the underground karst rock cavern, pinnacles and depths. The testing results can be used in the dam stability analysis as well as the curtain grouting design.
