摘　　要：主要探讨了锈蚀和荷载共同作用对钢筋混凝土拱桥承载力的影响。考虑钢筋锈蚀后截面面积减小、力学性能下降，混凝土保护层开裂，锈蚀钢筋与混凝土间粘结性能的退化等因素。In his paper, the load carrying capacity of corroded reinforced concrete arch bridges is mainly discussed. The reduction of steel cross section, the mechanical behavior deterioration of steel , the crack in concrete cover and the reduction of bond strength between concrete and steel are considered.

关 键 词：锈蚀 保护层开裂 粘结力 承载力 钢筋混凝土拱桥
