摘要
为比较应用于防治海水入侵工程的帷幕效果,建立剖面二维非均质流体的对流-弥散模型,运用伽辽金有限元法求解,并用物理实验结果验证其有效性。将模型应用于模拟广西北海市海城区海水入侵过程及对其防治效果,分别计算了超采地下水、实施防渗、抽水、注水和抽-注水情况下咸淡水界面随时间推移过程,通过比较得出注水是北海市防治海水入侵较为理想的措施。
The prevention of seawater intrusion through barriers is studied using a convectlon-dispersion numerical model of sectional two-dimensional non-uniform flow. The model is based on the Galerkin finite element method and the experiment, and applied to simulate the migration of the salt-fresh water interlace after exceedingly exploiting groundwater, adopting anti-seepage wall, extraction, injection, extrection-injection in Haicheng area in Beihai city, Guangxi. The conclusion is .that the injection is the optimal measurement for prevention of seawater intrusion in Beihai City.
