钢管混凝土拱桥拱肋吊装过程中的线形控制研究

Study on Linear Control during Hoisting of Ribs of Steel Tube Concrete Arch Bridges

钢管混凝土拱桥的拱肋吊装过程中的线性控制是当前研究的热点问题。以西南某钢管混凝土拱桥为依托,通过定长法控制扣索索力,优化扣索索力,从而对钢管混凝土拱桥拱肋吊装过程中线性的控制方法进行研究。希望能为钢管混凝土拱桥的施工和控制提供参考。

Linear control during lifting of ribs of steel tube concrete arch bridges is a hot problem in current researches.This paper,based on some steel tube concrete arch bridge in southwest,controls and optimizes cable force via the fixed length method so as to study the linear control methods during lifting of ribs of steel tube concrete arch bridges.It is expected that the research made by this paper is capable of providing a reference for construction and control of steel tube concrete arch bridges.
