Abstract: The transmission and matching performance of hollow-center optical fiber, self-diagnoseinspection of damage and crack in concrete were studied. Hollow-center optical filled adhesive was used to repair concrete automaticallly. The strength matching of concrete structure is considered to pro-vide a proof for hollow-center optical fiber used in concrete structure self-diagnose and self-repair. The whole system of self-diagnose and self-repair is put forward in detail. The experiment resultsconfirm the method feasibility finally.
