冻融环境再生混凝土结构耐久性模糊综合评估

摘要

According to the characteristic of recycled concrete structure damage in cold region,analyzed the influencing factors of recycled con-crete structure durability. With the fuzzy mathematical theory and diagnoses,established a durability assessment class,provides respective engi-neering evaluation calculation cases,which could be used to evaluate the recycled concrete structure in cold region.%根据寒冷地区再生混凝土结构的破坏特征，分析了影响钢筋混凝土结构耐久性的主要因素，综合运用模糊数学法与结构的实际调查分析，初步建立了钢筋混凝土结构耐久性评估等级，并给出了相应的工程评估算例，为寒冷地区再生混凝土结构耐久性评估提供了参考和依据。
