摘　　要：硫酸杆菌是造成市政混凝土排污管道腐蚀的一个重要原因。总结了近年来混凝土硫酸杆菌腐蚀的研究进展。针对混凝土硫酸杆菌腐蚀的研究方法分为细菌模拟测试和现场暴露测试。介绍了混凝土硫酸杆菌腐蚀与化学硫酸腐蚀的区别。国内该领域的研究尚属起步阶段,在腐蚀程度的评价以及预测模型的建立等方面的研究还很欠缺,建议加强这方面的工作。Thiobacillus corrosion is an important problem in sewer environment. The research progresses of thiobacillus corrosion on concrete in recent years are reviewed, and the corrosion mechanism is also introduced. The research of thiobacillus corrosion on concrete can be roughly divided into two groups; bacteria simulation tests and exposure tests in situ. In addition, the distinction between sulfuric acid corrosion and thiobacillus corrosion is explained. Though some advances have been made so far, there are a lot of void in the study of concrete corrosion resulted from thiobacillus. Especially the grading of the corrosion, the models for predicting corrosion rate should be intensified as soon as possible.
