摘要
分析了填海工程对地下水流动系统的影响和对地下水物理化学特征的影响,并通过有限元数值模拟的方法,研究了深圳地区填海工程对于海水入侵的影响,结果表明,当填海材料的渗透性越低、填海的规模越大、地下水位上升的越高时,咸淡水分界面往海洋方向移动的距离就越大,填海工程对海水入侵有一定的阻挡作用。
The influence of reclamation engineering on groundwater flow system and the influence on physical and chemical characteristics of groundwater were analyzed, and through the method of finite element numerical simulation, the effects of Shenzhen seawater intrusion under different circumstance of reclamation were studied. The research results show that, when the lower permeability of the filled medium, the bigger reclamation scale, the more high water level rose, the farther of the distance the interface between the fresh and brackish water moved to the sea. The reclamation project can play a part in the prevention of the seawater intrusion.
