Application of high density resistivity methods in exploring fracture water

High density resistivity method is used widely and is effective in detecting ground water. Ground water is usually enriched in the crack in granite tectonics area. High density resistivity method gathers a lot of electrode, which is an array way of D.C. electric method, so we can choose different electrode arrays according to different situation in actual application. Taking the effect of two detecting programs for examples, this article introduces how to choose fit detecting method due to different topography condition, different geologic geophysical condition in granite tectonics area.
