本文简要介绍地面电测深法，估算第四纪合水砂砾石层的孔除率和渗透系数的方法原理，并结合东宁－三岔口镇地下水资源勘察工作，估算第四纪含水砂砾石层的孔隙率与渗透系数。
This article briefly introduces the surface electric sounding method, the method of estimating the pore-water-cut rate and permeability coefficient of the Quaternary syn- chronized gravel layer. Combined with the investigation of groundwater resources in Dongning-Sanchakou Town, it is estimated that the Quaternary aquifer gravel Porosity and permeability coefficient.
