| Abstract: | Combined with the characteristics of Shanghai Longdong Avenue(Luoshan Road-G 1503)reconstruction project,the steel-concrete composite beam at P141-142 span is selected as the research object,and the construction technology of the anti-collision wall and the application of ultra-high performance concrete(UHPC)material in the anticollision wall are introduced.The results show that the compressive strength,flexural strength,bearing capacity,safety and corrosion resistance of the anti-collision wall poured with UHPC meet the design requirements,and the application effect is good,which can provide reference for similar projects. |
