多因素耦合作用下钢筋混凝土的腐蚀研究现状

Study on corrosion of reinforced concrete under multi factor coupling

混凝土结构通常受土壤环境水中硫酸盐和镁盐溶液的侵蚀。构筑物或建筑物都大量使用混凝土,若兰州地铁建设过程中地下水的可溶性镁盐、硫酸盐的含量过量时,则会对混凝土产生侵蚀作用,因而影响混凝土结构的寿命,甚至会造成严重的事故。因此研究多因素耦合作用下钢筋混凝土的腐蚀将对地铁结构的长期安全有重要的意义。

Concrete structure is usually affected by sulfate and magnesium salt solution in the soil water environment, the structure or building used a large number of concrete,if excessive content of soluble magnesium salt and sulfate in groundwater in the process of Lanzhou subway construction,it will cause erosion of concrete,thus affecting the life of concrete structure,even which will cause serious accident.So it is important to study the corrosion of reinforced concrete under the coupling action of multi factors,which will be of great significance to the long-term safety of the subway structure.
