曲线大跨度波形钢腹板PC箱梁精准安装

Accurate Installation of PC Box Girder with Curved Long-Span Corrugated Steel Webs

曲线大跨度波形钢腹板PC箱梁桥在施工建设中存在着波形钢腹板的高空精准安装问题,该问题在波形钢腹板PC箱梁桥的发展中造成一定阻碍,为了解决该问题,进一步优化施工质量,本文依据珊溪大桥研究了波形钢腹板在高空中的精准安装,得出了适用于钢腹板精准安装的施工理论,对于波形钢腹板PC箱梁桥的悬臂施工具有较强的指导作用。

Curved long-span corrugated steel web PC box girder bridges have a high-altitude precise installation of corrugated steel webs during construction.This problem has caused certain obstacles in the development of corrugated steel web PC box girder bridges.In order to solve this problem and further optimize the construction quality,this paper studies the precise installation of corrugated steel webs in high altitude based on the Shanxi Bridge,and derives a construction theory suitable for the precise installation of steel webs.For the PC box girder bridges with corrugated steel webs cantilever construction has a strong guiding role.
