淮安市政桥梁结构检测与安全评估

Damage Detection and Safety Evaluation of Huai'an Urban Bridges

桥梁结构是一种简洁高效的承力体系,作用在桥面上的外力荷载经桥面铺装传递给行车道板(即主梁上翼缘),桥墩和桥台支承主梁及其上部结构的自重,并将由主梁传递的外力荷载传递到基础和地基,最终传递到大地。主梁、桥墩、桥台等作为桥梁承力结构的主体,在荷载和环境因素长期作用下,不可避免出现安全隐患。文章在对淮安市区主要桥梁现场检测的基础上,分析总结桥梁承力体系存在的安全隐患,并说明相关检测手段。

The bridge structure is one of the succinct but high-efficient load-bearing systems, of which external forces acting at the surface will be transferred to the girder, the pier and abutment support the deadweight from upside structure and then diver the external forces to foundation and groundwork, at last, to the earth. The girder, pier and abutment are the main part of the bridge for bearing load, airways affected by the load and environment factor, so there are going to be incipient fanh in them. The article, according to the field detection of bridges, analyzes the safety incipient fault in the load-bearing system of bridge, and several methods of bridge detection are introduced.
