摘　　要：研究了空心光纤的传输特性与匹配特性、混凝土结构损伤、裂缝的自诊断检测以及利用注入粘度小的缩聚高分子溶液粘结修补剂来实现混凝土的自修复。论述了空心光纤与混凝土结构强度的匹配,为空心光纤用于混凝土结构损伤的自诊断与自修复提供了研究依据。对自诊断、自修复系统的总体方案进行了研究和分析,实验结果验证了该方案的可行性。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.
