Abstract

Aimed at the insufficient study on durability of reinforced concrete bridge under chloride attack,bidirectional electro-migration rehabilitation(BIEM) was applied to the bridges subject to chloride attack to improve the durability of concrete bearing platform in the water level varying areas.In accordance with the design data and measured data,certain parameters,including chloride diffusivity and surface chloride concentration,were obtained.Additionally,life prediction after bidirectional electro-migration rehabilitation could be realized by using the numerical solution of Fick's second law.The results show that BIEM is suitable for improving the concrete durability in water level varying areas.With the achievement of extending the service life of engineering applicants for ten years,BIEM can be an effective method to improve the durability of existed reinforced concrete bridges under chloride attack.
