曹妃甸某场地地下水腐蚀性变化规律分析

Analysing on Change Law of Groundwater Corrosion in a Site of Caofeidian

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。

In this poper, taking a project in Caofeidian as an example, the groundwater with different depths in this site are sampled and analyzed. According to the result of water quality analysis, the corrosion to the concrete structure and the steel bar in concrete structure by the corrosive media such as Cl-, SO2- , Mg^2＋ , total salinity and so on in shallow groundwater are analysed, and the change laws of corrosion along the vertical direction and horizontal direction are analysed. It has a guiding significance to design and calculate the corrosion in underground engineerings.
