摘要: 中国利用越流含水层作为城市供水水源地的实例并不多见。本文根据实际开采资料,利用伽略金(Galerkin)有限元法计算当补给层水头变化时越流含水层的地下水资源,并提出水位预测的方法。还利用补给层的水量平衡评价越流含水层开采量的保证程度,预测了新水源地投产后对老水源地的影响。本文对于正确认识越流含水层的地下水资源特性及其在城市供水中的意义有重要参考价值。

Abstract: The ground water resource in the leaky aquifer is evaluated by the Galerkin's finite element method on condition that the water table of the above recharge aquifer changes with pumping. The predication of the ground water head and influence on the old well field after the new wells come into operation is done by the method too. The guarantee of pumping rate is estimated by the method of water balance in phreatic aquifer. The results show that the quantity of leakage is 85% of pumping rate in the leaky aquifer. It is the reason why this area is rich in ground water resource. It is possible to establish a new well field the yield of which is 50-51 ×103m3/d.
