摘要
通过分析抽水引起含水层变形机理,推导出了考虑单元体位移的渗流方程,提出了抽水引起含水层变形对渗流场影响的数学模型。算例分析认为,在抽水渗流场定量计算时,单元体位移和含水层变形对渗流场都有一定的影响,特别是当弹性释水系数较小时,单元体位移对渗流场影响较大。
Through an analysis of aquifer deformation machanism caused by groundwater pumping,the seepage flow equation with considering adynamic unit is deduced in this paper,and the mathematical model for the effect of aquifer deformation caused by groundwater pumping upon seepage field is presented.The analysis of computation examples indicate that in quantity computation of seepage field by water pumping,adynamic unit and aquifer deformation may have a certain effect upon seepage field,and that particularly when elastic tripping water coefficient is small,the adynamic unit can affect the seepage field greatly.
