| 摘 要： | 在分析渗流井的结构与水流特征的基础上,通过引入等效渗透系数,结合当地地质、水文地质条件,构建渗流井取水的“渗流-管流”耦合模型,用于神木县张家川傍河水源地渗流井取水工程。确定水源地的布井方式与开采方案,计算水源地的平、枯水期允许开采量。结果得出：干水期允许开采量为35500 m3/d,枯水期允许开采量为11800 m3/d。

| Abstract: | By analyzing seepage wells ＆#39; structure, flow features as well as hydrogeological and geological characteristics of groundwater in Zhangjiachuan, Shenmu County, the paper induces equivalent penetration coefficient and establishes a＆quot;vadose flow- pipe flow＆quot; couling model of groundwater intaking from seepage wells to instruct field operations According to the model, allowa-ble exploitation amount in the period when the river level is at its normal level is 35 500 m3/d, while it in the period when the river level is lower than normal level is 11 800 m3/d. On the basis of research result, well distribution and exploitation plan are deter-mined. |
