摘要
以氯离子环境下检测到的钢筋局部腐蚀数据为基础,用最大腐蚀深度对钢筋局部锈蚀程度进行了描述。分析了最大腐蚀深度的分布类型,建立了局部腐蚀钢筋的可靠性模型,并进行实例验证分析,得出了一定腐蚀时间下腐蚀可靠性的发展规律,据此建立了局部腐蚀钢筋的可靠度计算方法。
Based on the local corrosion data of steel in the chloride environment, corrosion degree of steel was depicted by maximum corrosion depth.Distribution type of corrosion depth was analyzed.And reliability model of corrosion steel was established.Development law of corrosion reliability was discussed, a corrosion reliability calculation method was proposed.
