摘　　要：福州滨海新城濒临东海海岸,处于海水入侵范围内,海水入侵将导致土壤盐渍化、地下水水质恶化、腐蚀性变强等问题。通过对拟建福州地铁6号线延伸段各工点分层和混合地下水的水质分析,得出滨海新城区域海水入侵特征,并提出地下结构应对地下水腐蚀措施。Fuzhou Binhai New Town is close to the coast of the East China Sea and is within the scope of seawater intrusion.Seawater intrusion will lead to soil salinization,deterioration of groundwater quality and strong corrosivity.Through the analysis of the water quality of layered and mixed groundwater at each site of the extension section of Fuzhou Metro line 6,the characteristics of seawater intrusion in the area of Binhai New Town are obtained,and the measures for underground structure to deal with groundwater corrosion are put forward.
