Axial reinforcing method for reinforcing pipeline by using fiber composite material

The invention discloses an axial reinforcing method for reinforcing a pipeline by using a fiber composite material, which specifically comprises the following steps of: firstly, acquiring various characteristic parameters of the pipeline to be reinforced, a binder and the composite material, and controlling the shear stress of the binder to obtain the minimum axial reinforcing extension amount l of two sides of a defect of the pipeline to be detected; the adhesive is prevented from being debonded before the pipeline is yielded; and then the axial length d of the defect of the pipeline to be reinforced is measured, and reinforcement construction is conducted according to the preset adhesive thickness parameter and the total reinforcement length 2l + d. The method has the beneficial effects that it can be ensured that the binder is not debonded before the pipeline yields, and the reinforcing effect of the composite material is fully exerted. 本发明公开了一种利用纤维复合材料加固管道的轴向加固方法，具体为：首先获取待加固管道、粘结剂、复合材料的各特性参数，通过控制粘结剂的剪切应力，
