The steel plate wrapping method is used for solving the problem that longitudinal reinforcing bars in a reinforced concrete structure column are insufficient, and is a reinforcing method capable of greatly improving the section bearing capacity and the shock resistance. The carbon fiber pasting method is generally implemented by reinforcing the reinforced concrete structure column by adopting the transversely wrapped carbon fiber cloth, and because the constraint action of the carbon fiber cloth on the concrete is similar to that of the stirrup, the bearing capacity of the reinforced concrete structure column wrapped by the carbon fiber cloth is improved under the mutual compression action of three directions, so that a better reinforcing effect is achieved, but the method is easy to cause pasting, stripping and damage, so that the reinforced concrete structure column after being reinforced presents an obvious brittle failure form, and the reliability of the structure is influenced.
