摘　　要：采用室内砂槽模型试验研究了回灌井回灌过程中水丘变化规律与井深对补给效率的影响,通过观测地下水位变化,分析了不同井深条件下水丘变化规律,测定了不同时刻的回灌流量、出流量及总回灌量,基于试验的有效性分析了井深变化对总回灌量的影响。结果表明,回灌井与水丘位置关系决定水丘壅堵的效应,单位井深回灌量最大值出现于包气带与包气带井—潜水井的临界井深处。Indoor sand tank experiment is used to study on the water mound variation and the influence of well depth on the recharge efficiency during recharging process of recharge well. The water mound variation under the conditions of different welt depth is analyzed with observed groundwater level. Recharge flux, outflow at different time and the total recharge amount are measured. On the basis of the validity of experiment, the influence of well depth variation on the total recharge amount is analyzed. The results show that the position relationship between the recharge well and the water mound is decided by the water mound blocking effect and the maximum recharge capacity of unit depth appears at the critical depth between vadose zone well and phreatic well.
