摘要
闽清北溪闽江大桥与沿江的施工便桥形成T型交叉,通过在交接位置处的箱梁悬臂作加劲处理并布置横向预应力,解决了局部受力问题。
A T-shaped cross is formed between the Beixi Minjiang Bridge in Minqing and the construction bridge along the river. The problem of local stress is solved by stiffening the box girder cantilever at the junction and arranging the transverse prestress.
