Three Phases

This article surveys and studies the design, construction and verification codes related to durability of concrete bridges both home and abroad, contrastively analyzes their requirements on environmental effect, durability design, construction and testing indices, and finally brings up the durability index system suitable for Chinese concrete bridges which covers the four hierarchies of environment, material, components and structure, and also considers the three phases of design, construction and verification.

Critical Problems

The fundamental approach for solving the durability deficiency is to perform the durability design for planned concrete bridges and the durability maintenance for existing concrete bridges. Most of the existing durability design and maintenance methods, however, are qualitative and contain many subjective factors, which cannot solve the problems such as whether the structure is safe or not throughout the service life. The critical problems, such as the design service life, the environmental parameters, the material degradation process, as well as the lifetime performance assessment method, are found out based on deep insight into the existing concrete bridge durability design and maintenance methods. Finally, the schematics of concrete bridge durability design and maintenance methods that can quantitatively evaluate the degradation process of concrete bridges are proposed and the further research direction is determined.
