摘　　要：将结构自重作为损伤识别分析的外部信息,在此基础上分析混凝土裂缝损伤对结构的影响及其性质,从而找到能较好地反映结构损伤的物理量。通过光纤传感器和传统电测应变片的对比试验,验证了光纤传感器用于损伤识别的可行性。Making the structure weight as external information of damage identification analysis,on the basis of it,the effects and their natures of structure by concrete crack damages are analyzed,which can find the physical quantity that well reflectly the structural damage.The feasibility of damage identification by optical fiber sensor is verified through the contrast test between optical fiber sensor and traditional electric measurement strain gauge.
