湘西龙溪塘地区直流激电找水应用效果分析

湘西龙溪塘岩溶区,受NE向压性大断裂控制,岩溶发育具极不均匀性,断裂本身富水条件差.本文通过电法勘探,查明该区富水区域为次一级断裂或断裂两侧强岩溶发育带,并且平面和断面的视电阻率异常特征与强岩溶发育段密切相关.最后,通过分析激电异常,给出在该地区找水的几点建议.

Application Effect of DC IP Method in Searching for Groungwater at Longxitang in the Westren part of Hunan

The karst area of Longxitang in the western part of Hunan is controlled by NE extrusion rupture so the karst growth is very uneven, the rupture itself has poor condition for storing water. The article finds out the area in rich water is the first--degree rupture zone or two sides of the rupture is strong--karst growth zone by the method of electrical exploration. The abnormity feature of the visual resistivity of the plane and section has a close relation with the strong karst growth. At last, it gives some advice in searching of groundwater in this area by analyzing the DC IP abnormity.
