[提要]  结合混凝土结构在耐久性评价中包含许多模糊性因素的特点，将模糊数学的思想融入到生存分析法中，基于混凝土结构的耐久性失效准则，考虑删失数据的状态对混凝土结构耐久寿命的贡献，对混凝土结构耐久寿命进行了统计分析，算例表明分析结果比较合理。

Based on failure criterion of durability and characteristics of concrete structures, fuzzy theory is considered into survival analysis method. An example indicates that it is more reasonable to take the contribution of statement of truncation data into account for statistics results of durable life of concrete structures.
Keywords: concrete structures; durable life; fuzzy theory; survival analysis
