试论钢筋混凝土桥梁耐久性设计

Elementary Discussion on Durability Design of Steel Reinforced Concrete Bridge

钢筋混凝土结构的桥梁以其造价低廉和施工简便等优点得到了广泛的应用,但由于我国长期以来重强度、轻耐久性的设计理念,使得很多钢筋混凝土桥梁的使用寿命大打折扣,甚至发生严重的桥梁事故。基于此,对当前钢筋混凝土桥梁耐久性的主要影响因素进行了分析,在此基础上对钢筋混凝土桥梁耐久性的具体设计进行了探讨。

The steel reinforced concrete bridge is widely used because of its low construction cost and simple construction.However,its service life is greatly reduced owing to the design idea of paying attention to strength,and neglecting durability for a long time in China.Based on it,the article analyzes the main factors influencing the durability of steel reinforced concrete bridge now,and discusses the durability design of steel reinforced concrete bridge.
