该文以曹妃甸某工程为例,对该场地不同深度的地下水取样并进行水质分析。根据水质分析结果,判定浅层地下水中Cl~-、SO_4~(2-)、Mg~(2+)、总矿化度等腐蚀介质对混凝土结构及混凝土结构中钢筋的腐蚀性,并分析腐蚀性沿垂直方向及水平方向的变化规律,对地下工程的防腐设计和计算具有指导意义。 Taking a project of Caofeidian as an example, this paper samples the groundwater of different depths and analyzes the water quality. According to the result of water quality analysis, the corrosiveness of corrosion medium such as Cl ~ -, SO_4 ~ (2 -), Mg ~ (2+), total salinity and so on in the concrete structure and concrete structure was judged and the corrosion The variation of verticality and horizontal direction is of guiding significance to the anticorrosion design and calculation of underground engineering.
