摘要：
To study the factors affecting longitudinal corrosion cracks in concrete structures, the wet-dry cycle tests on 48 reinforced concrete specimens have been finished under natural conditions for two years. Based on it, the rule is analyzed how these factors e.g. concrete strength, cover thickness, bar diameter, stirrup spacing and corrosion ratio affect the longitudinal corrosion crack. The following conclusions can be drawn from this study. As the concrete strength and cover thickness rising up, the longitudinal corrosion cracks get thinner and thinner. With the stirrup spacing, the bar diameter and corrosion ratio increasing, the cracks become wider and wider.
