摘　　要：通过建立地下含水层水—热耦合数学模型,模拟分析不同含水层厚度下抽水井的温度变化,结合温度变化曲线,讨论了地下水源热泵抽灌井设计间距问题。结果表明,保持抽灌井间距不变,含水层厚度的增加可以减弱热贯通的影响;同一含水层厚度,可能在某一范围内改变抽灌井间距,热贯通程度变化不大;随着含水层厚度的增加,抽灌井设计间距总体呈现递减的趋势。Through the establishment of a mathematical model of underground aquifer which couples water flow with heat transfer,the temperature of pumping well was simulated and analyzed with different aquifer thickness,with temperature variation curve,the design spacing of groundwater heat pump pumping-injection wells was discussed.The simulation results show that,the effect of heat transfixion can be weakened with the increase of aquifer thickness by keeping the spacing of pumping-injection wells;With the same aquifer thickness,the spacing of pumping-injection wells may change within a certain range,but the heat transfixion degree does not change much.With the increase of aquifer thickness,the design spacing of pumping wells decreases.
