One of the two main types of aquifer is the unconfined aquifer.
非承压含水层是两种主要含水层之一.
The aquifer is unconfined locally and may be recharged.
含水层因为局部不承压而得到补给.
By taking the stagnation action of flow into consideration, the analytical solutions for computing drawdown and pumping rate is derived under the conditions of homogeneous, isotropical unconfined aquifer without recharge and of fixed drawdown in the pumping well.
文中推导出了在均质各向同性无上、下补给、定降深抽水条件下,考虑滞流作用时的变边界井流问题水位降落曲线及井的出水量的解析公式。
