摘要
为助力革命老区江西省宁都县脱贫攻坚和解决当地百姓生产生活用水问题,开展了此次找水打井工作。宁都县属白垩系红层地区,地下含水方式普遍为构造裂隙水。本文在前期水文地质调查工作基础上,采用高密度电法对重点工作区进行勘探,通过所测剖面反演出的电阻率拟断面图结合水文地质资料进行解译分析,然后定井,开孔验证后定井成功率100%,证实了高密度电法在红层地区找水的有效性和可靠性。
In order to help Ningdu County an old revolutionary base area in Jiangxi Province, to end poverty and solve the local people′s production and living water problems, the searching and drilling work for water well was conducted. Ningdu County is a Cretaceous red bed area, and the underground water mainly exists as structural fissure water. In this paper, based on the previous hydrogeological survey, the high-density electrical method was used to explore the key work area. The resistivity pseudo-cross-section of the measured profile was interpreted and analyzed in combination with the hydrogeological data, and then the well determination was conducted. The success rate of well determination after hole opening verification was 100%, which proved the effectiveness and reliability of the high-density electrical method in the red bed area.
