Resistivity Sounding Method in Mountainous Landslides Exploration and RGIS Application in Inversion Interpretation

As a regular indirect detecting geophysical exploration method with rapid and economic features and multiple solutions,electrical sounding mainly reflects different electrical properties of an exploratory object. The key of RGIS electrical sounding inversion interpretation makes utmost of the known geological data to set up strata and lithology parameters accordance with objective geological conditions,and to get correction coefficient K. Electrical sounding had been applied to a landslide mass exploration in a small hilly area of Lushi County. Complying with drill hole data,and with sufficient knowledge of geological and electrical characteristics of the exploration area,the inversion interpretation had applied RGIS software to infer distribution scope of the landslide mass and distribution feature of the sliding zone. The results show that the inferred electrical sounding interpretation coincides well with the actual geological conditions.
