摘要
在分析钢筋锈蚀造成钢筋混凝土构件力学性能退化的基础上,根据海港码头混凝土构件中钢筋锈蚀规律及混凝土保护层锈胀裂缝宽度与钢筋锈蚀深度的关系,建立了混凝土保护层锈胀开裂前和锈胀开裂后现役海港码头钢筋混凝土受弯构件承载力评估模型,可为现役海港码头钢筋混凝土结构耐久性评估及构件修复决策提供理论依据。
The mechanical .property deterioration of reinforced concrete members due to steel corrosion is analyzed. Appraisal models on the bearing capacity of reinforced concrete bending members of existing seaport structures before and after concrete cover＇ s cracking are set up according to the corrosion law of steel bars in reinforced concrete members at seaport structures and the relation between corrosion expanding crack＂ s width and steel bar＂ s corrosion depth. The appraisal models have laid a foundation for appraisal of durability and prediction of remaining service life of reinforced concrete members of seaport structures.
