摘要: 张集水源地是徐州市一个拟建水源地。了解浅层地下水动态变化规律是设计水源地最优取水方案、满足当地居民生活及工农业生产需水和水源地环境保护的重要前提条件之一。分析了水源地在现状以及不同开采条件下浅层地下水动态影响因素,建立了三维等参有限元数学模型模拟水源地地下水运动规律,利用大型群孔抽水试验资料进行参数识别和模型校正,预报了不同开采方案对水源地浅层地下水动态的影响,结果表明:水源地开采后,水源地开采将成为浅层地下水动态的主要影响因素之一;水源地允许开采量为13.71万m3/d是适合的,它不会引起地下水位的持续下降,不仅可满足当地居民用水需求,而且可以向徐州市稳定供水。

Abstract: Zhangji well field is going to be established in Xuzhou City.To know the characteristics of phreatic water dynamic drift is an important precondition for designing the optimal exploitation project, satisfying the water demands for the villager, agriculture and industry, and protecting the environment of the well field.Based on the hydrogeology characteristics, factors affecting phreatic water dynamic drift are analyzed under different exploitation conditions, a 3-D groundwater model is established by an isoparameteric finite element method.The data of pumping test are used for the identification and calibation of the model.The phreatic water table is predicted respectively under the exploitation projects.Results show that after the well field is established, pumping will become the main factor affecting the phreatic water dynamic.And that pumping rate is designed to be 137.1?103 m3/d is compatible.The pumping rate can make sure the groundwater table stable, also satisfy the water demands for local people, local industry, local agriculture, and Xuzhou City.
