摘要
利用生存分析中的生存函数乘积限估计方法分析水工混凝土结构的耐久寿命,结合混凝土结构耐久性失效的特点,将模糊综合评判法融入其中,研究耐久性评判等级和隶属度对水工混凝土结构耐久寿命估计的贡献,建立了删失示性函数模糊特征值的计算公式,得到使混凝土结构耐久性寿命统计更加合理的分析结果。
Durability life of hydraulic concrete structures is discussed by means of Product-Limit survival function estimation in survival analy- sis.Combined with characteristics of durability failure for concrete structures, fuzzy comprehensive evaluation method is practiced.Then durability assessment level and membership to durability life estimate for hydraulic concrete structures is studied.As a result, a fuzzy eigenvalue formula about censored indicator function is established.More reasonable life expectancy statistics analysis results on durability of concrete structures can be obtained by this method.
