摘　　要：介绍了地下水源热泵的工作原理,通过实验,确定了第四系砂砾含水层地区的回灌井渗透系数和最佳的回扬强度、回扬时间和回扬时间间隔,比较了连续回灌不回扬和定期回扬时回灌井的渗透系数。The operating principle of underground water source heat pump is introduced. The infiltration coefficient of artificial recharge well in the quaternary gravel aquifer area, the optimal pump lifting intensity, the pump lifting time and the pump lifting interval are determined through experiments. The infiltration coefficients of artificial recharge wells during continuous artificial recharge without pump lifting and with periodical pump lifting are compared.
