摘　　要：针对20世纪建设的大量码头因长期运营于恶劣环境而产生的钢筋混凝土劣化问题,依托宁波舟山港二期码头加固修复工程,设计不同的玄武岩纤维制品进行针对性加固修复,包括采用双层玄武岩纤维布(300~380 g/m^(2))结合粘接胶对面板进行加固、植入玄武岩纤维筋结合钢套筒支模灌注C40水下不分散混凝土进行加大截面法加固、掺入玄武岩纤维网格结合混凝土进行面层控裂加固等,结合施工工艺流程实现了将玄武岩纤维布、筋、网格在老码头中的综合应用,并对施工后约2年的应用效果进行评估。结果表明,玄武岩纤维布未出现鼓包、剥离等现象,玄武岩纤维网格、筋复合混凝土结构未产生有害裂缝,总体外观质量良好。In response to the deterioration of reinforced concrete caused by long-term operation in harsh environments in a large number of whaves built in the twentieth century,relying on the reinforcement and repair project of Ningbo-Zhoushan Port phase II wharf,we design different basalt fiber products to use for targeted reinforcement and repair,which include using double-layer basalt fiber cloth(300 g m^(2) to 380 g m^(2))combined with adhesive to reinforce the panel,implanting basalt fiber reinforcement combined with steel sleeve support formwork to inject C40 underwater non-dispersed concrete for increased cross-section method,and adding basalt fiber mesh combined with concrete for surface layer crack control reinforcement.Combining with the construction process,we achieve the comprehensive application of basalt fiber cloth,reinforcement,and mesh in the old wharf,and evaluate the application effect of about 2 years after construction.The results show that there is no bulging or peeling phenomenon in the basalt fiber cloth,and there are no harmful cracks in the basalt fiber mesh and reinforcement composite concrete structure.The overall appearance quality is well.
