Study on Durability and Reliable Design Method of Marine Concrete Structures under Load and Environment Coupling Effects

The durability model of service life prediction for reinforced concrete structures under load and environment coupling effects, that according with the characteristics of projects in china, was established in the scientific research project of Study on Durability and Reliable Design Method of Marine Concrete Structures under Load and Environment Coupling Effects which was taken by CCCC 4th Harbor Institute, by making use of the self-designed dynamic load and chloride coupling durability test equipment to carry out concrete durability testing. The research results have been included in "Standard for Durability Design of Port and Waterway Engineering Structure" and relevant specifications, which can directly guide the engineering technician engaged in marine concrete structure durability design to carry out durability life calculation and prediction work for reinforced concrete structures. The results have been achieved the technological breakthroughs of concrete structural durability from “experience in design” to "quantitative reliability in design". Currently, the results have been successfully applied to Zhanjiang Port renovation project of No. 405 and 406 Berths.
