引用地表水回灌补给地下水，在咸淡水前锋形成一道带状阻咸帷幕屏障，是防治海水入侵的一项有效工程措施．但是，淡水帷幕的形成与咸淡水界面推移的速度和推移时间等因素之间的定量分析是人们十分关注的问题．本文借助物理模型的模拟方法对上述问题进行了试验研究，并探索该项措施的可行性和防治效果．该项试验可为淡水帷幕工程措施防治海（咸）水入侵技术研究提供最基本的试验室依据．
Using surface water recharge to recharge groundwater and forming a strip-like barrier against salt water in the brackish water front is an effective engineering measure to prevent and control sea water intrusion. However, the quantitative analysis of the factors such as the speed of freshwater curtain and the time of transition between brackish water and brackish water is a problem of great concern. In this paper, the physical model of the simulation method for the above problems were studied, and explore the feasibility of this measure and control effect. This test can provide the most basic laboratory basis for the research on freshwater curtain engineering measures to prevent and treat sea (salt) water intrusion.
