沿海吹填造陆中填泥类型对地下水腐蚀性影响

The influence of mud filling type on the corrosiveness of groundwater in reclamation land in coastal area

沿海地区地下水盐类离子含量高,对混凝土结构及其内部的钢筋造成腐蚀。以不同的填泥类型为切入点,首次考察沿海地区吹填中河底淤泥和海泥对地下水腐蚀性的影响。选取了天津地区具有代表性的两个区域作为研究对象,分析潜水水样和土样,评价腐蚀性。结果表明,河底淤泥替代海泥进行吹填,能有效降低地下水盐类离子含量,从而减轻地下水的腐蚀性。

The salt ion content of groundwater in coastal area is high,which causes corrosion to concrete structure and its internal reinforcement.In this paper,the influence of river bottom silt and sea mud on the corrosivity of groundwater in the reclamation of coastal areas is studied.The two representative areas of Tianjin were selected as the research areas,and the groundwater and soil samples are taken for analysis to evaluate the corrosivity.The results showed that the river bottom silt can effectively reduce the salt ion content of groundwater and reduce the corrosiveness of groundwater.
