Through the analysis of the factors which affect bridge anti-seismic,26 sub-factors are selected, and evaluation index system is set up for bridge seismic from bridge structure,seismic design,repair maintenance, seismic equipment and site condition five aspects,a bridge seismic safety is analyzed in Guangzhou city.The re-sults show that the conclusion of multi-level fuzzy comprehensive evaluation is consistent with the actual situation, and repair maintenance is the weakest link,multi-level fuzzy comprehensive evaluation method can provide refer-ence for the prevention of building and other projects.%在对影响桥梁抗震性能的因素进行分析的基础上，选取了26项对桥梁抗震安全性影响较大的子因素作为评价指标，从桥梁结构、基坑设计、维修养护、抗震设备和场地条件等5个方面，建立了桥梁抗震多级模糊综合评价体系，并对广州市某一特大桥抗震安全性的进行了分析。结果表明，多级模糊综合理论评价方法的计算结果与实际桥梁服役情况相符合，维修养护是此桥梁抗震安全性的薄弱环节，多级模糊综合理论的评价方法为建筑及其他工程抗震防灾方面的提供参考和借鉴。
