Abstract: This paper introduces the basic principles, distribution and data inversion method of the high-density resistivity method. The artificial leakage with low resistance at Outang dam verified the practicality and reliability of high-density electrical method. The test results shows that the high-density resistivity method has a good detection effect for low resistivity and anomaly area, and provides a scientific basis for judgment of dam leakage.
