摘　　要：结合工程实例,秀英港7号、8号泊位码头存在失稳倾覆风险,为保证码头的正常使用和生产,提出码头修复加固方案。针对码头基床掏空区域,设置水下钢筋笼并抛石,侧面采用石坝封堵,形成局部封闭区域,浇筑水下不分散混凝土并进行二次压浆的方案进行修复;针对方块倾覆区域,设置预制L形挡板,侧面采用橡胶气囊封堵,形成局部封闭区域,浇筑水下不分散混凝土并进行二次压浆的方案进行修复。项目实施取得了良好的施工效果,可为类似工程提供借鉴。According to the project example,in view of the area of wharf foundation bed hollowing out,underwater steel cage and stone throwing are set up,and stone dams are used on both sides of the gap area between the steel cage and foundation bed hollowing out,and underwater non-dispersed concrete is poured and secondary grouting is carried out for restoration.For the overturning area of the block,a prefabricated L-shaped baffle is set up,and rubber air bags are used on both sides of the gap area between the baffle and the overturning area of the block,and underwater non-dispersed concrete is poured and secondary grouting is carried out for repair.The implementation of the project has achieved good construction results,which can provide referencefor similar projects.
