滨海盐渍土易溶盐及其腐蚀性与垂向分布的关系

Relationship between soluble salt and its corrosivity in coastal saline soil and vertical distribution

通过潍坊北部沿海地区盐渍土试验研究,分析易溶盐含盐量、Cl^(-)和SO_(4)^(2-)含量的垂向分布特征。结果表明:研究区土质以氯盐型盐渍土为主,易溶盐含量随土层深度的增加而逐渐减少并趋于稳定,土质中Cl^(-)和SO_(4)^(2-)是本区域最主要的腐蚀因子,显示对混凝土和钢筋具有中-强腐蚀性作用。

Through experimental research on saline soil in the northern coastal area of Weifang,the vertical distribution characteristics of soluble salt content,Cl^(-),SO_(4)^(2-)content were analyzed.The results show that the soil in the study area is mainly composed of chloride salt saline soil,and the soluble salt content gradually decreases and tends to stabilize with the increase of soil depth.Cl^(-)and SO_(4)^(2-)in the soils are the most dominant corrosion factors in the region,showing moderately-strong corrosive effects on concrete and steel reinforcement.
