高密度电法在卢氏县水文地质勘察中的应用

Application of High Density Electrical Method in Hydrogeological Investigation of Lushi County

高密度电法在旱区地质勘察、水资源探测等领域应用广泛。采用高密度电法,通过对河南省卢氏县某研究区域的水文地质条件进行探测,获得5条剖面的电法数据,进行解译后得出每条探测剖面的视电阻率剖面及地质推断解释图,对结果进行分析可知,此区域内的探测结果可分为两大类:一类视电阻率大致集中在30Ω·m^50Ω·m之间,可将其视为第四系黄土层;另一类视电阻率主要以大于80Ω·m^100Ω·m为主,可将其视为砾、卵石层,整个研究区域内地层富水性中等,具备成井条件。

High-density electrical methods are widely used in geological exploration and water resources detection in arid regions. Using high-density electrical method, the hydrogeological conditions of a research area in Lushi County,Henan Province were detected, and the electrical data of five sections were obtained. After interpretation, the apparent resistivity profile and geological inference of each detection profile were obtained. Explain the graph and analyze the results. The results of this region can be divided into two categories: one class of appa rent resistivity is roughly concentrated between 30 Ω·m and 50 Ω·m, which can be regarded as the Quaternary loess layer;The apparent resistivity is mainly from more than 80 Ω·m to 100 Ω·m, which can be regarded as gravel and pebble layer. The formation is rich in water in the whole research area and has well-forming conditions.
