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。
The project was established in the early 1970s. Due to its long service life and the long-term exposure of some structures, the structure has been deteriorated and damaged. Taking into account the safety of the subsequent use of the pier project, the structural layout of the project, the apparent damage and reinforcement corrosion, concrete carbonation depth and compressive strength of reinforced concrete components, reinforcement distribution and protective layer thickness, the overall structural verticality Conducted a comprehensive test, and according to the corresponding test results and specifications of the main structure of the carrying capacity of review. On this basis, the comprehensive assessment of the safety of the pier structure provides the basis for the subsequent structural restoration and reinforcement, and provides a reference for similar projects.
