新疆阿图什哈拉峻地区地下水系统模型研究

Study on groundwater system model of Halajun Area in Xinjiang Autonomous Region

根据阿图什哈拉峻地区地下水系统水文地质特征,采用系统分解合成方法,在单一的潜水、承压水地下水模型子系统基础上,建立了冲洪积扇地区地下水数学模型。用有限元方法对模型进行数值离散,利用DevelopStudio软件编制计算程序,对边界条件及垂向水交换量进行动态模拟,对潜水和承压水稳定流静态流场、非稳定流动态流场进行了拟合,得到了该地区地下水系统水文地质参数,参数分布与水文地质勘察所得含水层结构特点及富水区分布基本相符。

The mathematical model of groundwater system for pluvial alluvial region in Halajun Area is established based on the subsystem models for simulating the phreatic water and confined water by using analysis-synthesis method.The FEM is applied to numerically discrete the model and the computational program is developed by utilizing the software DEVELOP STUDIO.The hydrogeological parameters of the system are obtained from the simulation of flow fields for steady flow and unsteady flow of phreatic water and confined water.The result approximately accords with exploration data.
