A series of problems will appear for high-pile wharf after years of operation, which will influence the wharf’s safe operation and structure durability. On the basis of the investigation and analysis of the appearance,and combining concrete strength of structure component and reinforcement cover thickness and carbonation depth in concrete, this paper analyses the current technical condition for a ten years’ high-pile wharf, the results of which may serve as a scientific basis for the consolidation maintenance and upgrading rebuilding.
