摘要
淡水帷幕的形成与咸淡水界面推移速度和推移时间等因素之间的定量分析是海水入侵防治中引入关注的问题,该文基于耦合的饱和-非饱和多孔介质的水流和溶质运移控制方程,采用FEMWATER三维软件系统,模拟分析了在不同的流量边界和浓度边界下淡水帷幕的演化规律.数值模拟结果表明,淡水回灌流量对淡水帷幕形成的影响十分显著,采用淡水帷幕技术防治海水入侵是一个十分有效的方法.
The quantititive analysis of the rule of the fresh water purdah forming and the fresh-salt water in- terface moving is the concerned problem.The paper considering the water flow and solute transport cou- pling governing equations in porus medium,using the FEM underround water simulation sysytem-FEM- WATR to simulae and analyze the fresh water puurdah evolution law with diferent flow and concentration boundarys.The simulation results indicates that fresh water replenishment flow has evidence impact on fresh water purdah forming and fresh water purdah is the powerful method to prevent and cure salt water intrusion.
