[摘要] 工程始建于20世纪70年代早期，由于服役时间较久以及部分结构的长期外露，结构已有一定劣化、损伤。考虑到该码头工程后续使用的安全性，对该工程的结构布置、表观损伤与钢筋锈蚀情况、钢筋混凝土构件的混凝土碳化深度及抗压强度、钢筋分布和保护层厚度、结构整体垂直度情况等进行了全面的检测，并依据相应的检测结果及规范对其主体结构进行了承载能力复核。在此基础上，对码头结构的安全性进行了综合评定，为后续的结构修复与加固提供了依据，并为同类工程提供参考。

Abstract: The engineering was established in the early 1970s. Because of the long service time and long-term exposure of some parts of the structure,a certain degree of deterioration and damage has occurred to 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.A bearing capacity check about the main structure was made according to the corresponding detection results and standards. On these basis, the safety of the wharf structure was comprehensively assessed, and some suggestion about repairing, reinforcement and maintenance was provided. It provides the basis for the follow-up of repair and reinforcement,can be referred by sinular engineering.

Keywords: aged wharf; safety inspection; bearing capacity check
