陕化需水量不断增加,原水源地已不能满足用水要求,需要寻找新的水源地。新开水源地开采井位于遇仙河和石堤河之间,渭河大堤以南200m左右。本文对新开水源地建立了水文地质概念模型,并运用目前国际通用的可视标准软件Visual ModFlow对勘察区地下水进行了数值模拟计算和预测,得出了该区在多年平均降水量的条件下,新增加的开采量主要靠渭河激发补给和蒸发量减少的结论。
Increasing demand for water in Shaanxi, the original source of water has been unable to meet the water requirements, the need to find new water sources. The newly opened water exploration well is located between the Xianxian River and Shidi River, about 200m south of the Weihe River embankment. In this paper, a hydrogeological conceptual model was established for the newly opened water source area and the groundwater in the survey area was calculated and predicted by using Visual ModFlow, a common international visual standard software. The results show that under the conditions of multi-year average precipitation , The newly increased extraction mainly rely on the Weihe River to stimulate the supply and reduce the evaporation conclusion.
