摘要
桥面板在桥梁结构中直接承受交通荷载是桥梁结构体系的重要组成部分。随着重型车辆的增加和桥梁服役时间的增长,发现部分桥梁结构中桥面板受损严重,因此针对桥面板发展出了一系列的加固修复方法。围绕国内外桥面板加固的技术的研究发展现状,介绍了外贴钢板加固,FRP材料加固(外贴FRP片材加固,外部FRP(筋)格栅加固,体外预应力FRP筋加固和嵌入式FRP筋材)技术的应用和研究发展情况,分析其优点与不足,以促进针对桥面板加固方法的研究工作的开展。
Bridge deck in bridge structure bearing directly the traffic load is an important part of the bridge structure system.With the increase of heavy vehicles and the bridge service time,bridge decks in part of the bridge structure are found severely damaged,so a series of strengthening and repairing methods have been developed. This paper reveals the research and development of different strengthening design procedures,which are applied to improve the structural performance of bridge decks,discussing and presenting the advantage and limitation of those strengthening methods by studying the application of different strengthening methods,including external bonding steel plates and FRP material strengthening method（ external FRP sheets,external FRP grid,external prestressed FRP tendons and the near surface mounted FRP rods）,which can improve the researches related to strengthening technology in bridge deck structures.
