摘　　要：研究了碳纤维铆钉在码头结构开裂、损伤及耐久性变化后的加固作用,并比较了不同加固方式的优缺点。以实际工程为例,通过不同加固条件下的钢筋混凝土循环实验,建立了不同碳纤维(CFRP)加固方式在循环荷载作用下,钢筋混凝土构件循环峰值与标准构件极限荷载之比和极限承载力下降幅度的曲线关系,得到碳纤维加固方式对剩余承载力的影响规律及符合试验的最佳锚固长度。The reinforcement effect of carbon fiber anchors on cracking, damage and durability change of wharf structure is studied, and the advantages and disadvantages of different reinforcement methods are compared. Taking the actual project as an example, through the cyclic tests of reinforced concrete under different reinforcement conditions, a curve relationship between the ratio of the cyclic peak value of the reinforced concrete elements to the ultimate load of the standard elements and the reduction of the ultimate bearing capacity under cyclic loading with different carbon fiber(CFRP) reinforcement methods is established, and the influence law of the carbon fiber reinforcement method on the residual bearing capacity and the optimal anchorage length consistent with the test are obtained.
