| 摘 要： | 本文通过外加电流阳极极化法试验来研究混凝土结构中钢筋锈蚀产生的顺筋裂缝问题 ,探讨钢筋的腐蚀率、混凝土质量、保护层厚度以及钢筋在混凝土中的位置等因素对于顺筋裂缝的产生和发展所起作用 ;随后在大量试验数据和已有工程调查的基础上总结出钢筋直径损失的分阶段预测公式。

| Abstract: | Study on longitudinal crack of R.C.structure induced by corrosion of steel bar embedded in concrete were studied through extra impressed current.The effects of some elements on initiation and development of crack were also discussed,including corrosion rate,concrete quality,concrete cover and location of steel har in concrete.finally,on the basis of a large quantity of experiment data and site investigation,the formula to predict diameter loss of reinforcing bar were concluded.
