摘要
地下水腐蚀引起钢筋锈蚀并最终导致混凝土结构破坏是地下结构最普遍和严重的破坏形式。论文采用规范中地下水对混凝土和钢筋腐蚀性检测方法开展了唐山市曹妃甸区地下水腐蚀性检测评价,并就中等腐蚀和强腐蚀的硫酸盐和氯盐进行危害性讨论,研究成果有助于该地区地下结构的防腐蚀设计。
The most common and serious form of damage to underground structures is concrete structure damage caused by groundwater corrosion and corrosion of steel bars.In this paper,the corrosivity test and evaluation of groundwater in Caofeidian District of Tangshan city were carried out by using the corrosivity test method of groundwater to concrete and reinforcement in the code.Then,the hazards of highly corrosive sulfate and moderate corrosive chloride salts were discussed.The research results are helpful for the anticorrosion design of underground structures in the area.
