Abstract

In the water shortage area of karst mountain in northwest Hunan, the terrain condition is complex and the electromagnetic interference is strong. In the groundwater exploration, the DC method with strong anti-interference capability is preferred. The engineering practice shows that, when the terrain is relatively gentle and the exploration depth is relatively shallow (about 0~150 m), the small distance combined section method of apparent resistivity + high-density resistivity method is adopted, and when the terrain condition is poor or when the exploration depth is relatively deep (about 0~400 m), the small distance combined section method of apparent resistivity and three-pole IP sounding method are used, and proper inversion and interpretation are carried out, which not only improves the working efficiency but also solves the practical problems, and achieves better water finding effect.

Key words： DC method water exploration karst area strong electromagnetic interference northwest Hunan
