摘　　要：以在役混凝土桥梁结构耐久性三层次多指标评估模型为基础,对海洋环境下影响混凝土桥梁结构耐久性的因素进行分析,确定海洋环境下构件的耐久性考核指标对各个模糊等级的隶属度。最后用杭州湾跨海大桥为例,验证评估方法的合理性。Based on the three - level - muhi - index evaluating model, the factors influencing the durability of concrete bridges structures in marine environment are analyzed in this paper and then the membership degree of durability test indexes at various fuzzy levels is determined. In the end, taking Hangzhou Bay Bridge as an example, this evaluating method is proved reasonable. The presented method is of simplicity, practicability and clear aim with reference value to durability evaluation of bridges in other chlorine environment.
