Abstract:UHPC is a cement-based material with ultra-high mechanical performance and ultra-long durability, and it provides new possibility for innovation and performance promotion in bridge structures. In recent years,both domestic and oversea scholars have continuously performed a series of researches on UHPC in the field of bridge structures,driven relevant engineering applications,and made remarkable progresses. This paper introduces several new types of UHPC-based high performance bridge structures investigated by the authors’ research team,including the innovative UHPC strengthening structure for in-service steel bridge deck with fatigue cracking,UHPC strengthening structure for dangerous and degraded concrete bridges, UHPC bridge deck with shallow ribs,long-span UHPC box girder bridges,middle and short-span UHPC prefabricated bridges,UHPC-NC composite bridges,prefabricated UHPC cab beams,and UHPC anti-collision structures. The characteristic and advantage,theoretical and experimental researches,and engineering application of these new structures are systematically presented,aiming to provide experience for research and application of UHPC-based high performance bridge structures.
