摘　　要：为了研究渗流井在陕北佳县南河底水源地的取水效果,通过建立研究区的地下水流三维数值模型,模拟了渗流井取水结构在开采条件下的出水情况。对比分析了渗流井在单井、群井作用下的出水量情况,建议不同时期的开采量为:平水期72 300 m3/d,枯水期47 600 m3/d;指出用渗流井开采水资源时,井间干扰较小。与相同开采技术条件下的管井及廊道模型模拟结果对比,表明渗流井取水结构的出水量大,供水保证率高,并且在建议开采量下含水层的水位降在允许范围内。Based on the analysis of hydrogeological conditions in Nanhedi of Jia County,Yulin,Shaanxi,a numerical model was developed to simulate the allowable yield of seepage well in the exploitation conditions.The paper work out the allowable water-supply： in median water period,the allowable water-supply is 72300 m3/d;and in the dry period,the allowable water-supply is 47600 m3/d.When seepage wells are used to exploit water resources the inter-well interference is relatively small.Through the analysis of the simulation results of three different water-supplying projects（seepage well,galleries and large-diameter well）,a conclusion was made that the seepage well had many advantages compared to large-diameter wells or galleries in the study area,such as the lager reasonable yield,the higher assuring rate and the much less influence on local hydrogeological conditions.
