中小跨径公路桥梁抗震防落梁构造措施探讨

Discussion on Anti-seismic and Anti-drop Beam Construction Measures of Small and Medium Span Highway Bridges

中小跨径桥梁是公路基础设施的主要组成部分,以钢筋混凝土为主要材料的上部梁板在破坏性地震中落梁现象常有发生。针对这个问题,对近几年来一些桥梁结构中采用的抗震防落梁构造措施进行初步的汇总和探讨。

Small and medium span bridge is the main component of highway infrastructure.In destructive earthquakes,upper beam and slab often fall off,whose material is mainly reinforced concrete.According to this problem,anti-seismic and anti-drop beam construction measures adopted in bridge structure in recent years are summarized and discussed preliminarily.
