【摘要】 国内外地铁工程中混凝土结构被腐蚀的报道越来越多,人们通过对于地铁结构因所处位置和环境特征进行研究,分析出对其混凝土结构腐蚀有多种因素,如杂散电流,氯离子等。通过评述两种影响因素对混凝土产生腐蚀影响研究现状,指出对研究地铁混凝土结构腐蚀的方向。更多还原

【Abstract】 More and more problems about the corrosion of concrete structures in subway engineerings have been reported at home and abroad.Through the study and analysis for the location and environmental characteristics of subway,many factors that would cause the corrosion of concrete structures are determined,such as the stray current,chloride ion and so on.At the same time,through the discussion on the current situation of research on the above two influencing factors,i.e.the stray current and chloride ion,the research direction for the corrosion of concrete structures in subway engineerings is pointed out.更多还原
