摘　　要：由于古塔样式多、分布广,且损坏情况各不相同,传统加固措施对于古塔的保护往往难以取得很好的效果。近年来随着碳纤维材料的广泛应用,为塔类加固提供了一种经济安全、方便快捷的新途径。根据某古塔加固实例,设计了一种碳纤维修复补强方案,并通过有限元程序分析了加固前后该古塔的抗震性能。分析结果表明,此种加固方法能够很好地满足塔类砌体结构在地震作用下的抗震要求。Protection of cultural heritage structures such as the ancient pagoda from severe earthquake by conventional strengthening methods is not always reliable. In recent years carbon fiber reinforced polymer（CFRP） has been widely applied to the field of rehabilitation and retrofit of existing structures, so earthquake protection of cultural heritage structures through FRP is practicable and feasible. The seismic properties of the old tower and that with FRP are analyzed. The calculated results illustrate that the strengthening method with FRP is very effective to improve the structure＇s earthquake resistance and has great potential specifically for use in ancient masonry structures.
