PHASE-MODEL OF CORROSION RATE OF STEEL BAR UNDER CHLORIDE ENVIRONMENT
-
摘要: 在探讨了现有钢筋腐蚀速度模型缺陷的基础上,建立了氯离子侵蚀下钢筋腐蚀速度的分阶段预测模型。该模型针对锈蚀开裂前后混凝土对钢筋保护作用的不同,分阶段地建立了锈蚀开裂前后的钢筋腐蚀速度随机模型。该模型的建立对于正确预测和分析氯离子侵蚀环境下钢筋混凝土结构的可靠性和剩余寿命奠定了理论基础。Abstract: Based on the discussion on default of corrosion rate of steel bar, phase-model of predicting corrosion rate is constructed.Aimed at the difference of effect of concrete on steel bar, random model of corrosion rate is established before and after crack, which will provide a theoretical basis for predicting reliability and residual life of reinforced concrete structures under chloride environment.
