Health Evaluation for Durability of Harbor Engineering in South China Based on AHP

Considering the corrosion degree of reinforcement, the chloride penetration resistance of concrete and chloride concentration distribution in concrete, a health evaluation method for durability of harbor engineering was established by analytic hierarchy process (AHP). Analysis of a harbor in South China demonstrates that the health indicator for durability condition of existing structures can be effectively used to quantitatively health evaluation for durability of practical engineering.
