After considering the actual dimension of reinforced concrete structure, the thickness and geometrical boundary condition of concrete cover, the model of corrosion-induced expansion can be simplified as a plane model of semi-infinite body. Through theoretical analysis, formulas are got to calculate corrosion-induced expansive stress of concrete cover. The results shows that: the corrosion-induced crack originated on the interface between concrete and the corrosion layer, if initial cracking is not in vertical direction to the surface of concrete cover, cracks along the rebar induced by the uplift and horizontal tension stress on the surface of the concrete cover may occur from its outer to inner, it also presents that the anti-rust ability of reinforced concrete structures could be improved by increasing the thickness of concrete cover, raising the grade of concrete, and increasing the diameter of rebar. Compared with the existing literatures, the precision of the theoretical solutions is verified.
