摘　　要：按照《碳纤维片材加固混凝土结构技术规程》与《混凝土结构加固设计规范》分别对胶锚或钢板锚、环形箍及自锁式、加织物压条一般式3种U形箍加锚方式加固后的梁斜截面承载力进行计算。结果发现,2种计算方式得出胶锚或钢板锚加锚方式的承载力增加值差异最小,加织物压条一般式的差异最大。2个工程抗剪加固应用算例的验证结果与计算结果一致。由此可知,在相同加固要求条件下,采用胶锚或钢板锚加锚方式的加固成本最低。According to the Technical Specification for Strengthening Concrete Structures with Carbon Fiber Reinforced Polymer Laminate and the Code for Design of Strengthening Concrete Structures,the bearing capacity of the inclined section of the beam reinforced by three kinds of U-shaped hoop anchoring methods,such as rubber anchor or steel plate anchor,ring hoop and self-locking anchor and general fabric layer anchor,is calculated.The results show that the difference of the added value of the bearing capacity of the rubber anchor or steel plate anchor is the smallest,and the difference of the general fabric layer anchor is the largest.The results of two engineering shear reinforcement application examples are consistent with the calculation results.It can be seen that under the same reinforcement requirements,the reinforcement cost of using rubber anchor or steel plate anchor is the lowest.
