摘　　要：浅层地下水对地下建筑具有一定的腐蚀性,影响建筑物安全,沿海地区尤为严重。随着曹妃甸新区城市建设的加快,浅层地下水和土对工程的腐蚀性及对工程结构设计的影响也越来越受到关注。本文对曹妃甸滨海区的地下水腐蚀性数据进行了统计分析,并对地下水的侵蚀性进行了评价,得出曹妃甸滨海区域地下水腐蚀性的规律。浅层地下水对混凝土结构具有弱-强的腐蚀性,自北向南逐渐加重;对混凝土结构中的钢筋普遍具有腐蚀性,对钢结构具有弱-中等腐蚀性,总体向南加重。此研究可以为区内的城市规划和工程建设提供借鉴。Shallow groundwater have corrosion effection to underground buildings in a certain degree, affecting the safety of buildings, especially in coastal areas. With the acceleration of urban construction in Caofeidian area, Hebei Province, the influence of the corrosiveness of shallow groundwater on engineering structure has been paid more and more attention. This paper makes statistical analysis of groundwater corrosion data in Caofeidian coastal area, and evaluates the corrosion of groundwater, and obtains the rules of groundwater corrosiveness in Caofeidian coastal area. The shallow groundwater is weak- strong corrosive to the concrete structure, and gradually aggravates from north to south. It is generally weak- corrosive to the steel in the concrete structure, weak- moderate corrosive to the steel structure, and generally aggravates to the south. The results can provide reference for urban planning and construction in the area.
