摘　　要：资源型回灌是城市建设工程保护地下水的有效措施之一。为在回灌设计中合理考虑群井效应的影响,采用在选定的回灌区内动态调整回灌井数量和间距的现场试验方法,研究了群井效应对单井回灌量的影响,总结了单井回灌量随井数、井间距的变化规律。结果表明,群井效应对单井回灌量影响显著,回灌区面积一定时,单井回灌量随回灌井数量的增加呈明显下降趋势,单井回灌量与回灌井间距呈近似对数关系。Recharge is one of the effective measures to protect groundwater resources in urban construction.To reasonably consider the influence of group well effect in the design of a recharge project,the influence of group well effect on the recharge capacity of a single well was experimentally studied by adjusting the number and spacing of recharge wells dynamically in the selected recharge area,and the change law of the recharge capacity of a single well with the number and spacing of recharge wells was summarized.The results show that the group well effect has a significant effect on the recharge capacity of a single well.Once the recharge area is selected,the recharge capacity of a single well decreases with the increase of the number of recharge wells,and the relationship between the recharge capacity of a single well and the spacing of recharge wells is roughly logarithmic.
