哑铃形拱肋压注混凝土力学分析

Mechanical Analysis of Pressure Injection Concrete for Dumbbell Shaped Arch Ribs

常州市中天钢铁运河大桥是一座下承式系杆拱桥。结合施工过程,分析压注混凝土时液态混凝土压强对钢管及腹板的作用,提出了哑铃形钢管压注混凝土的合理顺序及相应的腹板加强方案,可作为设计及施工时的参考。

The Zhongtian iron and steel canal bridge in Changzhou is a through tied arch bridge. Combined with the construction process, this paper analyzes the effect of liquid concrete pressure on steel pipe and web, and puts forward the rational sequence of dumbbell shaped steel pipe pressure grouting concrete and the corresponding reinforcing plan of web, which can be used as a reference for design and construction.
