| 摘 要： | 该文介绍了拉杆在小跨径拱桥设计中的应用。四方东部新区二号线跨河西河桥全长29.3 m,桥型采用钢筋混凝土刚架板拱桥,下部结构为肋板台,桩基。设计时在两承台间设置预应力混凝土拉杆以抵抗水平推力,减小桩基数量,降低造价。该技术可供类似的工程参考。

| Abstract: | The article introduces the application of pull rob in the design of small-span design.The total length of the bridge crossing Hexi River in Sifang Eastern New Area II Line is 29.3 meters.The bridge is a steel reinforced concrete rigid-frame plate arch bridge.The substructure is the ribbed slab platform with pile foundation.The prestressed concrete pull rods is installed between two base slabs in design to resist the horizontal thrust,to decrease the number of pile foundation and to reduce the construction cost.This technique can be referred for the similar projects. |
