The high resolution resistivity method is a ten-year research achievement of Australia's ZZ Resistivity Imaging Research Center in the resistivity exploration method.It created a brand new concept in resistivity data acquisition and data processing and is large improvement to the traditional data acquisition method.This new method can acquire data of all possible electrode combinations from only one layout of a set of electrodes.Such it can collect more than 40 times of the traditional resistivity data acquisition configuration.The new method completely abandons the psudosection geometry factor concepts,and calculates true resistivity sections from survey data directly with an inversion technique.Currently,there still is no effective geophysical method that can accurately detect caves under rough surface topography.We use the new method to explore caves in Karst of airports,mined laneways,the small mined region of susarface and tunnels with complicated geological conditions.By drlling the new method can reach over 60 percent of accuracy.So we can say that the experiments completed with the new method show that this method can produce very promising results.In a word,the new method has some reference values for engineering explorations under complicated geological conditions.
