Durability design of a sea-crossing bridge in Zhejiang Province was carried out. Exposure condition of the marine environment was divided into four zones, i.e., atmospheric zone, splash zone, tidal zone and subsea zone. Environment condition surrounding the bridge was introduced, and then the factors affecting the deterioration of the concrete structure were analyzed. It was found that the main factor was chloride ions invasion. Then a chloride ion intrusion model was built based on Fick’s second law. Design parameters corrected by Fully Probabilistic Method were used. Besides, the effect of stress on chloride diffusion coefficient was also considered. Using a variety of supplementary cementitious materials, the concrete mix was examined by Rapid Chloride Migration Tests to meet durability requirements. Finally, through capillary crystalline technology, the resistance to chloride ion penetration was further enhanced.
