钢筋混凝土碳化可靠度评估方法研究

摘要

介绍了钢筋混凝土结构的混凝土碳化机理及碳化深度模型，建立了以分析时间为起点的混凝土碳化可靠度分析及剩余碳化寿命预测模型，并研究了其近似计算方法。以实际工程为案例，对其碳化可靠度及剩余碳化寿命进行预测，为该结构的维修加固决策提供了建议。%This paper introduced the concrete carbonation mechanism and carbonation depth model of reinforced concrete structure, established the concrete carbonization reliability analysis and remaining carbonation life prediction model as analysis time for starting point, and studied its approximate calculation methods. Take practical engineering for case example, predicted the carbonization reliability and remaining carbonation life, provided suggestions for reinforcement and repair decision-making of this structure.
