钢筋混凝土桥梁耐久性研究

Durability of Reinforced Concrete Bridge

钢筋混凝土结构桥梁近年来应用日益广泛,但随着桥梁服役时间的增加,桥梁的耐久性问题也越来越突出。对服役的桥梁进行检修,不仅耗费财力物力,还大大的影响交通。作者从钢筋混凝土材料及钢筋混凝土结构碳化深度对钢筋混凝土桥梁的耐久性进行研究,并提出提高混凝土桥梁耐久性的措施,可为桥梁耐久性设计提供参考。

Reinforced concrete bridge structures used widely in recent years,but with the increase of service time of the bridge,the durability of the bridge has become increasingly prominent.The bridge of service for maintenance,not only consume financial and material resources,but also greatly affect traffic.From the reinforced concrete and reinforced concrete structures carbonation depth of concrete bridge durability study and propose measures to improve the durability of concrete bridge,the bridge can be designed to provide a reference for durability.
