Safety Inspection and Evaluation on the Main Structure of a Framework Wharf

摘要

Yiyang rubber machinery group cargo terminal is a vertical frame wharf established in the early 1970's. A certain degree of deterioration and damage has occurred to the structure because of the long service time and long-term exposure of some parts of the structure. Taken the subsequent use of safety into account, the structure was completely detected. The detection content included array of structure, apparent damage and rebar corrosion situation, carbonation depth and compressive strength of concrete, distributions of reinforcement and cover thickness, verticality of the overall structure and so on. The bearing capacity of the main structure was checked according to the corresponding detection results and standards. Then the safety of the wharf structure was comprehensively assessed and some suggestion about repairing and reinforcement was also made which could provide the reference for the follow-up repair and reinforcement or other similar engineering.
