摘　　要：介绍了波形钢-混凝土组合桥面板在实际工程中的应用概况及力学性能研究现状。研究成果表明:(1)与混凝土桥面板相比,该新型组合桥面板自重轻,且具有较高的抗弯承载力和刚度;与钢桥面板相比,该新型组合桥面板抗疲劳性能优异。基于以上优点,该新型组合桥面板具有广阔的应用前景。(2)目前针对波形钢-普通混凝土组合桥面板开展的研究主要集中在组合桥面板的静力性能上,需要对其疲劳性能开展更多的理论及试验研究;目前针对波形钢-超高性能混凝土组合桥面板的相关研究较少,需要对其开展更多的静力性能和疲劳性能研究。(3)将超高性能混凝土应用于该新型组合桥面板中,合理选择剪力连接件型式,在保证波形钢板与混凝土之间可靠连接的前提下,进一步减少焊缝数量,提高其抗疲劳性能,是该新型组合桥面板的发展方向。The applications in the actual engineering and research status of corrugated sheet steel-concrete composite bridge decks are introduced.Research results show that:(1)Compared with concrete bridge decks,the new composite bridge deck has light weight,while has a higher bending capacity and rigidity.Compared with steel bridge decks,the new composite bridge deck has more excellent anti-fatigue resistance.Based on the above advantages,the new composite bridge deck has a broad application prospect.(2)At present,the research on the corrugated sheet steel-normal concrete composite bridge deck mainly focuses on the static property,and more theoretical and experimental studies on its fatigue property are needed.There are little research on the corrugated sheet steel-ultra-high performance concrete composite bridge deck,and more researches on its static and fatigue properties are needed.(3)Adopting the ultra-high performance concrete,selecting the shear connector type reasonably,reducing the number of welds on the premise of ensuring the reliable connection between corrugated sheet steel and concrete,and improving its fatigue resistance are the developing direction of this new compositebridgedecks.
