摘要
以莘县为例,探讨傍河井抽取的地下水与引黄河水之间存在的关系。研究结果表明,引黄沟渠在抽水井影响半径2倍以外时,傍河井的数量或者抽水量足以引起引黄沟渠周围区域性地下水位下降,则引黄河水对该区域的地下水补给量就会增加,取水量越大,地下水位下降越大,补给量增加的也越多;当引黄沟渠在抽水影响半径2倍之内时,引黄河水就会直接补给水井,补给量与水井的单位时间出水量、水井与引黄沟渠的距离、抽水时间有关,出水量越大、距离越近、抽水时间越长,引黄河水的侧渗补给量越大,反之依然。
This paper takes Shen County as the example,researches the relationship between taking water from well of approach Yellow River and piloting water from Yellow River.The research indicates that pilots water from drainage and ditch of Yellow River,in water well 2 times pull out outside the water well radius of influence,when well quantity or the pump output causes sufficiently pilots around drainage and ditch of Yellow River the regional subsoil water level to drop,will then make the ground water supplies quantity to increase.Takes the water volume to be bigger,the subsoil water level drops is bigger,supplies the quantity to increase are also more.When pilots water from drainage and ditch of Yellow River 2 time of pump radius of influence,Yellow River water pilot water well directly,supply the quantity and water well＇s unit interval/unit time water discharge,the distance of well and drainage and ditch of Yellow River,the pump time related,the water discharge will be bigger,the distance to be nearer,the pump time to be longer,pilots the Yellow River water the side to infiltrate the supplies quantity to be bigger,otherwise still.
