摘　　要：反滤回灌井是地下水库中一种有效的回灌设施,它由回灌井和井口的反滤层组成。完整反滤回灌井井流运动由反滤层的竖向流和完整井的水平流组合而成,文中提出了承压-潜水含水层中完整反滤回灌井稳定流的计算方法,结合实例说明了反滤回灌井的回灌量大大低于普通回灌井的回灌量,并分析了反滤层、井损、回灌堵塞和影响半径等因素对回灌量的影响。The structure form and well flow characteristics of recharge well with filter layer in the groundwater reservoir is introduced and the steady flow calculation of completely recharge well with filter layer in the confinedunconfined aquifer is brought forward, the influences of filter layer, well loss and recharge clogging upon recharge volumes is then analyzed.
