摘　　要：桥梁承担着交通运输、跨江跨海、城市景观的功能。钢筋混凝土简支空心板梁桥结构简单、自重相对较轻、受荷明确,因而较多应用于中小跨径公路桥梁中,是我国高速公路、城市道路及地方道路路网建设的主力桥型之一。随着桥梁服役年限的增长,已建桥梁的病害数量增多。及时发现关键病害并进行养护,可以降低钢筋混凝土板梁桥的不安全因素。通过分析管养数据库,以钢筋混凝土板梁桥为研究对象,运用Python程序,对其病害特征进行分析,为提高混凝土板梁桥结构的服役寿命提供依据。Bridges undertake the functions of transportation,over-river,and urban landscape.Because of its simple structure,relative light weight,clear load,reinforced concrete simply supported hollow slab girder bridges are mostly used in middle-small span highway bridge.It is one of the main bridge types used in the development of China′s highway,metropolitan road,and local road networks.The number of bridge diseases increases with the time going.Finding bridge major diseases in time and maintenance management can reduce the risk factors of reinforced concrete slab girder bridges.Using the management database as the research object,a Python program was used to analyze the disease characteristics of the reinforced concrete slab girder bridge,which provides the foundation for improving the service life of the concrete slab girder bridge structure.
