| 摘 要： | 通过染色和摄像技术成功地在室内１０００×２００×２０ｍｍ的砂槽内模拟了均质条件下淡水帷幕的形成和发展过程。在３个不同的回灌流量和３种不同的咸水浓度（１、５、１０ｇ／ｌ）的人工回灌条件下，咸淡水界面呈现出现良好的突变界面特征；淡水帷幕的形成主要受回灌流量的影响，咸淡水密度差对其影响很小；帷幕的形成呈现出良好的规律性，其纵向横向发展与回灌时间的关系可分别用幕函数和线性函数来近似。

| Abstract: | Existing several projects show that fresh water barrier can be effectively used to prevent sea water intrusion and protect aquifer.In this research,formation of fresh water barrier is successfully simulated in 1ab through dying fresh water and video techniques with a 100020020mm sand box.Under artificial recharge situation,freshsalt water frontier is typical abrupt interface,the formation of fresh water barrier is primarily affected by recharging water rate,affection of density difference is really limit.Basically,the lateral and vertical developments of frontier are linear and powerful functions of time respectively. |

| Keywords: | fresh water barrier rate concentration |
