摘　　要：实际结构往往承受各种荷载的作用,考虑荷载对混凝土结构耐久性的影响是非常必要的。钢筋锈蚀是影响混凝土耐久性的重要因素之一,研究荷载对钢筋腐蚀的影响对探究服役下钢筋混凝土结构耐久性问题有重要意义。综述了荷载及荷载与其他因素耦合作用对混凝土中钢筋腐蚀的研究进展,总结了现有的考虑荷载影响的钢筋锈蚀模型,并结合当前研究存在的问题进行了总结和展望。Taking the effects of load in the study of the durability of concrete structures into consideration is very essential, because structures always suffer from many forces.The corrosion of reinforcing steels in concrete is one of the vital reason for the deterioration of concrete durability.It is of significance to study the influence of loadingon steel corrosion for the durability of existing RC structures.This paper reviews previous studies carried out to investigate the effects of load and simultaneous load and other factors on the bar corrosion in concrete.Some existing bar corrosion models are also concluded.According to issues in the current research,the trends and prospects are presented finally.
