With the charaCTeristics of simplicity and quickness, multi-electrode resistivity method can find out the important landslide geological information such as the thickness, the range and the developmental characteristics of the landslide body in landslide geological hazards exploration; and then, through drill hole deployment, the physical-mechanical parameters which are indispensable to work out the stability calculation can be obtained. The testing results indicate that multi-electrode resistivity technology performs well in the exploration of landslide body, the result is the same as the reflection seismic total deviation detection technology, and the relevant geological parameters acquired can provide a basis for the evaluation and control of landslide.
