摘　　要：结合我国桥涵设计规范和两类桥梁用钢筋腐蚀后力学性能退化的实验数据,对氯盐类融雪剂引起的钢筋腐蚀对桥梁安全性的影响进行了分析,并根据试验数据得出钢筋质量腐蚀率与钢筋力学性能退化的数值关系,得到了钢筋质量腐蚀率与桥梁安全性的初步规律,并根据试验数据及现象,提出桥梁钢筋锈蚀问题的评价标准。The corrosion of two kinds of steel bars is studied in this paper according to the code for the design of reinforced concrete bridges. The effects of steel bars＇ corrosion caused by the chloride snow -melting agent on the saftey of RC bridges are analysed. The numerical relations between the corrosion state and the degeneration of mechanical performance are studied based on the experimental data. And preliminary laws between saftey of bridges and mass loss ratio of steel bars are studied. According to the phenomenon and data of experiment,the evaluation standard of steel bars in bridge is put forward ,which can be the references for the engineering practice.
