摘　　要：钢筋混凝土结构的广泛应用使建筑物在使用过程中面临多种潜在的损坏因素。浙江义乌上吴渡槽属于内陆地区且常年处于湿热环境中,该区域施工中混凝土结构的耐久性主要受到混凝土碳化的影响,因此,采用混凝土碳化模型对上吴渡槽混凝土碳化寿命进行预测具有重要意义。预测结果表明:上吴渡槽排架部位碳化寿命为70年,渡槽修建距今约50年,剩余碳化寿命为20年。该结果对于老旧渡槽的碳化寿命预测有一定参考价值。The widespread application of reinforced concrete structures poses various potential damage factors to buildings during use.The location of Shangwu Aqueduct in Yiwu,Zhejiang Province,is an inland area and is constantly in a humid and hot environment.The durability of concrete structures in this area is mainly affected by concrete carbonation,so it is of great significance to predict the carbonation life of the concrete in Shangwu Aqueduct by concrete carbonation model.The prediction results indicate that the carbonization life of the bent parts of Shangwu Aqueduct is 70 years,and the aqueduct was built 50 years ago,with a remaining carbonization life of 20 years.It provides certain reference value for predicting the carbonization life of old aqueducts.
