滁河大桥大跨径预应力混凝土连续箱梁桥设计

Design of Large- Span Prestressed Concrete Continuous Box Girder Bridge of Chuhe River Bridge

介绍了南京滁河大桥的桥型方案、总体设计以及主桥的结构设计特点。该主桥为左幅(48+85+52)m和右幅(52+85+48)m的左右幅错孔布置的三跨变截面预应力混凝土连续箱梁桥。其工程的设计经验,可供其它类似桥梁工程借鉴或参考。

The bridge type scheme, overall design and structural design features of main bridge of Nanjing Cbuhe River Bridge are introduced. The main bridge is a prestressed concrete continuous box girder bridge with the three -span variable cross -section arranged by staggered holes on both left （48 ＋ 85 ＋ 52 ）m and fight （52 ＋ 85 ＋ 48） m sections. The design experience of the project can provide reference for other similar bridge engineering.
