桥梁病害成因分析与加固设计

Cause Analysis and Reinforcement Design of Bridge Diseases

摘要:

近年来随着经济的快速发展，交通流量持续增长，一些建设较早的钢筋混凝土桥梁由于使用年限的增加，出现影响结构耐久性乃至安全性的病害，为保证桥梁的设计使用年限，采取有针对性的维修加固措施是必要的。以某收费站桥为工程实例，通过对钢筋混凝土桥病害的调查，分析病害产生的原因并进行加固方案设计，详细分析了钢筋混凝土桥梁的维修加固流程，为类似工程的维修加固设计提供一定的参考。

Abstract:

In recent years, with the rapid development of economic construction and the continuous growth of traffic flow, some early-built reinforced concrete bridges have shown diseases that affect structural durability and even safety as their service life increases. To ensure the design service life of bridges, it is necessary to adopt the targeted maintenance and reinforcement measures. Taking a toll station bridge as an engineering case, through the investigation of the diseases of reinforced concrete bridges, the causes of diseases are analyzed, and the reinforcement schemes are designed. The maintenance and reinforcement processes of reinforcement concrete bridges are analyzed in detail. Some references are provided for the maintenance and reinforcement design of similar projects.
