高墩大跨径预应力刚构—连续组合梁桥施工

主要以西阳河特大桥为依托工程,介绍了在高墩大跨径预应力刚构—连续组合梁桥悬臂施工线形控制中的理论分析、参数修正和施工高程控制方法,并提出设置短期预拱度与长期预拱度的方法,以保证成桥后的桥梁线形符合设计目标线形。

Cantilever construction of the prestressing rigid structure-continuous composite beam bridge with high pier and large span

Taking the Xiyanghe large bridge as relying project,it introduces theory analysis,index correction and construction high control method of line type control of the cantilever construction on the prestresing rigid structure-continuous composite beam bridge with high pier and large span,and provides method of setting short period camber and long term camber,so as to ensure bridge line type after completed bridge satisfy design aim line type.
