钢管混凝土拱桥拱肋吊装过程的线形优化方法

Study of Line-shape Optimizing Method About Rib-assembling Coursing of Concrete Filled Steel Tubular Arc Bridges

针对南里渡特大桥钢管拱肋吊装的施工工艺 ,提出了模拟该过程的两阶段拱肋线形优化方法。通过对整个过程的模拟分析 。

According to the construction technology about rib assembling coursing of NanLiDu Long Span Arc Bridges of Concrete Filled Steel Tubular,the two stage line shape optimizing method is presented in this paper which simulates of the whole procedure. By this simulation analysis of the whole procedure, this method can satisfies the need of design precision in efficiency.
