摘　　要：对中卫市某傍河地下水源地辐射井的井位优化进行总结和分析,根据水文地质勘察报告,水源地为傍河(多泥沙河流)水源地,水文地质条件复杂,渗透系数不均,且水源地内发育有古河床。同时考虑到辐射井单井造价高,因此选择合适井位以达到最大单井出水量显得尤为重要。井位优化方法的基本原则,包括考虑地下水源地的地质特征、河流的水动力特征及水文地质条件和环境保护要求。通过合理的井位优化,辐射井平均单井出水量达到9800 m3/d,最大程度地发挥了其作用,提高地下水的开采效率和水质的稳定性。This article provides a simple summary and analysis based on the engineering practice of a riverbank underground water source well in Zhongwei City,according to the hydrogeological survey report,the water source is a riverbank(with abundant sediment)water source,characterized by complex hydrogeological conditions,non-uniform permeability coefficients,and the presence of ancient riverbeds within the water source area.Considering the high cost of constructing individual radiation wells,it is particularly important to select suitable well locations to achieve maximum water yield.The basic principles of well location optimization include considering the geological characteristics of the underground water source area,the hydraulic characteristics of the river,as well as the hydrogeological conditions and environmental protection requirements.Through reasonable well location optimization,the average water yield per well of the radiation wells in the riverbank underground water source reached 10,000 m/d,maximizing the role of the wells and improving the efficiency of groundwater extraction and the stability of water quality.
