摘要
首先论述了玛纳斯河流域山前平原地下水系统的结构特征和地下水的循环模式,由山前到沙漠边缘可分为三个带:水平径流带、溢出带和垂向交替带。运用有限单元法建立了双层含水层地下水流数值模拟模型,并阐明了模型中对混合开采井、泉和地下水蒸发等特殊问题的处理方法。给出了应用模型对研究区水文地质进行定量研究的结果:评价地下水补给资源量和可开采资源量,预测一定开采条件下的泉流量变化趋势。
System structure characteristics and cycle pattern of groundwater in plain of Manas valley was first presented. In a view of groundwater movement, plain was divided into three zones: horizontal flow zone, overflow zone and the zone of vertical exchange. And then a groundwater flow of two lays was modeled using finite element method, in which some of special problems were dealt with, for example, mixed pumping, spring, and evaporation of groundwater. Model is used to deal with groundwater recharge rate and safe yield, forecasting spring rate under special pumping paln.
