叙述了桥梁加固设计中选择使用碳纤维片材及其粘接材料时应注意的几个问题 ,并且阐述了这些问题对碳纤维设计强度取值的影响 ,最后提出了采用分项系数法来定义这些影响 Some problems that should be paid attention to in the selection of carbon fiber sheets and their bonding materials are described in the bridge reinforcement design. The influences of these problems on the design strength of carbon fiber are also discussed. Finally, the method of using the sub-coefficient method to define these effects
