摘　　要：介绍了三极断面测深技术在第四系水源地勘探中的应用。钻探验证结果表明 ,该方法能够准确地圈定第四系地层中的含水体 ,可为供水水源地选择提供必要的地质资料。Third-pole sectional depth sounding, an electrical resistivity sounding method, is effective for the delineation of aquifers in quaternary strata according to the distribution of natural or artificial electric fields underground semi-space. The appraisal of water-bearing characters for the upper strata is a main geological aim on basis of the technical demands of electrical resistivity sounding. As a great transverse change in Quaternary sediment facies and poor continuity, the method is selected to protrude the electric abnormal characters of lends-shaped sand bodies for increasing resolution of electrical prospecting and offering essential geological data for the selection of headwater area of water delivery.
