摘要
唐白河大桥主桥上部结构为(40+60+60+40)m四跨一联预应力混凝土箱形变截面连续梁,主墩为钢筋混凝土空心薄壁墩,基础为承台加钻孔灌注桩。介绍主桥上部结构及下部结构的设计,为今后中等跨径连续梁安全、经济、合理的设计提供有益的参考。
The superstructure of the main bridge of Tangbaihe River Bridge is a prestressed concrete continuous box girder with variable cross section,comprising 4 spans of (40+60+60+40) m in one continuous unit. The piers of the Bridge are designed as hollow section thin-wall reinforced concrete piers resting on bored pile foundations. In this paper, the design of both the superstructure and substructure are presented, which provide helpful references to the reliable, economic and reasonable design of the medium-span continuous girders.
