摘要：Drilling a well randomly would lead to high uncertainties and could not meet the demand of water supply from the increasing population.It is in dire need to improve success rate of well drilling.The high-density resistivity method offers us a good choice.In this study,high-density resistivity method is used for groundwater survey in five villages in the Taobei District of Baicheng.The data obtained by high-density resistivity method is inverted through Res2dinv software.It is found that the electrical structure is characterized by a horizontal layer distribution,and the resistivity shows a"high-medium low-low"feature from shallow to deep.Moreover,obvious electrical gradient zones are identified in the strata below each section,which are interpreted as tectonic weak zones,i.e.,the faults.The low-resistance anomaly areas are inferred to be favorable aquifers.The results show that high-density resistivity exploration is an efficient and practical method for determining water well sites in rural areas and can provide a guide for finding water resources in the area.
