摘　　要：为解决枣庄市峨山镇三山村高效农业用地缺乏灌溉水源的问题,采用水文地质调查结合直流电阻率测深的方法对区域内地下灌溉水源地分布情况开展调查研究。前期通过水文地质调查了解区内主要地下含水层岩性及富水特征,在此基础上结合已知井分布位置,确定2处有利的地下水源地部位,在对应位置开展直流电阻率测深。后期结合已知井揭示的地层空间分布特征和直流电阻率方法获取的电阻率曲线数据进行综合分析解译,推断主要富水地层为泥质灰岩地层,发育深度在50~110 m区间,在2处测深点部位进行了钻探验证,揭示含水层为泥质灰岩地层,埋藏深度分布在57.68~100.1 m区间,2眼井涌水量均在50 m^(3)/h左右,满足了当地灌溉水源的需求,基于直流电阻率方法推断的含水层埋深与钻井揭示的实际情况基本一致,应用效果明显。In order to solve the problem of lack of irrigation water source in high-efficiency agricultural land in Sanshan village,Eshan town,Zaozhuang city,the method of hydrogeological survey combined with cirect current(DC)resistivity sounding was used to investigate the distribution of underground irrigation water source of the region.The lithology and water-rich characteristics of the main underground aquifers in the area were accomplished by the previous hydrogeological survey.On this basis,combined with the known well distribution locations,two favorable underground water source locations were determined,and DC resistivity sounding was carried out at the corresponding locations.Then combined with the spatial distribution characteristics of strata revealed by known wells and the resistivity curve data obtained by DC resistivity method,comprehensive analysis and interpretation were carried out,and it was concluded that the main water-rich strata were argillaceous limestone strata with a depth of 50~110m.Drilling verification was carried out at two sounding points,revealing that the aquifer was argillaceous limestone strata.The burial depth was distributed in the range of 57.68~100.1m,and the water inflow of the two wells was about 50 m^(3)/h,meeting the demand of local irrigation water source.The aquifer burial depth inferred based on DC resistivity method was basically consistent with the actual situation revealed by drilling,indicating its obvious application effect.
