数值法模拟赵油坊水源地深层地下水允许开采量

Numerical simulation for evaluating allowed water exploitation from deep aquifer in Zhaoyoufang

摘要: 通过抽水试验,确定了拟建水源地——赵油坊的水文地质参数:平均导水系数878.27m²/d,弹性释水系数为6.85×10^-4,压力传导系数为1.55×10⁶m²/d,水跃值为3.44m;根据水文地质参数把水源地划分为6个单元。选用合理的计算模型,模拟不同开采条件下地下水水位下降情况,确定以24000m³/d的开采方案较为合理。

Abstract: Hydrological parameters of groundwater resources zone in Zhaoyoufang are attained by pump experi-ment.The mean conductivity coefficient,elastic storage coefficient,pressure conductivity coefficient,hydraulic jump value are 878.27 m²/d,6.85×10^-4,1.55×10⁶ m²/d,3.44 m,respectively.Based on those parameters,the groundwater resources zone is divided into 6 units.Selecting the proper model to simulate groundwater level change under different exploitation condition,it shows that No.1 exploiting 24 000 m³/d design is more reasonable.
