综合物探方法在凤阳石灰岩地区水资源勘查中的应用

Application of combined geophysical methods in water resources exploration in the Fengyang limestone area

凤阳县石灰岩地区地下水勘查,主要是通过物探方法识别有储水条件的构造断裂、岩溶及地下暗河。通过合理布设物探测线,利用电阻率联合剖面法和高密度电法相结合,能够有效识别断层、地层界线、软弱夹层、岩溶等不良地质体,是凤阳县石灰岩地区地下水勘查工作中值得推广的物探组合方法。本文以凤阳县西泉镇某工业园区地下水资源勘查工作为例,介绍了利用电阻率联合剖面法和高密度电法相结合,进行水资源勘查的工作流程,可以为该地区类似工作提供技术借鉴。

Groundwater exploration in the limestone area of Fengyang County is mainly to identify structural faults, karst and underground rivers with water storage conditions by geophysical methods. Faults, strata boundaries, weak interlayers, karst and other undesirable geological bodies can be identified effectively by reasonable arrangement of geophysical survey lines and by combined use of resistivity profile method and high density electrical method, which is worth popularizing in groundwater exploration in the limestone area of Fengyang County. Taking the groundwater exploration work in an industrial park in Xiquan Town, Fengyang County as an example, this paper introduces the working process for water resources exploration using both resistivity profile method and high-density electricity method, which can provide technical reference for carrying out similar work in this area.
