| 摘 要： | 渗流井是一种结构较为复杂且有别于水平井及其他井孔的取水建筑物，利用河床砂砾石层的净化作用，将河水转化为地下水以获得水资源，该工程在干旱半干旱地区作用尤为显著。通过引入“等效渗透系数”，建立研究区的地下水流三维数值模型，分别模拟计算了平水期和枯水期渗流井的出水量，最终确定大会坪研究区的建议开采量为30600 m3/d。

| Abstract: | The seepage well is a kind of water-fetching building, which has a complicated structure and is different from the horizontal wells and other wellholes. Taking advantage of purification effect of the riverbed aquifers, the seepage well can transform river water into groundwater so as to obtain water resource. The effect of the project is more remarkable in arid and semi-arid areas. By introducing the equivalent hydraulic conductivity, a three dimensional numerical model was developed to simulate the allowable yield of seepage well in the normal and dry seasons. Analysis indicates that the allowable water yield of Dahuiping water source area should be 30 600 m3/d. |
