Abstract: Geophysics is advanced technology with high- speed and undamaged compared with other methods in detecting delects in embankment. The foundation of analyzing the cause and finding out the position of dam leakage, and taking corresponding renovate methods can be offered by geophysics prospecting. Application of high- density resistivity teehnology to caves is introduced by taking the soil damin Shandong province as an example.
